Disgraced British actor John Alford has been found dead in prison, aged 54.

The actor, known for his roles on UK TV series “London’s Burning” and “Grange Hill”, was in custody following a string of sex offenses connected to two teenage girls in 2022.

He was sentenced to eight years and six months in January this year.

His death was confirmed by The Mirror, who shared a statement from a prison spokesperson.

“John Shannon died in prison on 13 March 2026,” it read.

“As with all deaths in custody, the Prisons and Probation Ombudsman will investigate.”

Alford’s real surname was Shannon, though he used the former as his stage name.

According to The Sun, Alford was found unresponsive in his bed at the Category C HMP Bure in Norfolk. While medics were called, the actor did not wake despite their attempts.

“He didn’t wake up in the morning. He was in his bed and they thought he was just asleep,” a source told the publication.

“When they tried to wake him there was no response and they realized he was dead.”

The actor rose to fame in the 1980s thanks to his role as rebel Robbie Wright in the BBC teen drama “Grange Hill”. He was just 13 at the time. He later moved on to star as fireman Billy Ray in “London’s Burning” in the 1990s.

Despite his popularity on the program, Alford’s career on TV was short-lived. He was famously sacked from the TV series after he was convicted for supplying cocaine and cannabis.

He was sentenced to nine months in jail in 1999, serving just six weeks behind bars.

He briefly broke back into acting in the early 2000s but found himself in trouble with the law once again in 2018 when he was charged for resisting a police officer.

At the time of his death, Alford was only months into serving out a sentence connected to the assaults of two young females.

The actor attacked the two girls, aged 14 and 15, while they were drunk after a night out at a pub in April 2022.

Alford was staying at a friend’s Hertfordshire house, also the father to a third girl, at the time of the assault.

The trial heard he had intercourse with the 14-year-old female and touched the 15-year-old inappropriately while she was half asleep.

Chris White, from the Crown Prosecution Service, said the disgraced star was “fully aware of the girls’ ages, yet he chose to exploit them,” as per Sky News.

The actor was found guilty on four counts of sexual activity with one girl and sexual assault and assault by penetration relating to the other at St Albans Crown Court in September last year.

At the time, he insisted the jury’s guilty verdict was “wrong”.

The homeless brute who allegedly stole an 88-year-old lady’s cane in Union Square — and knocked her over while trying to flee with her purse — is a registered sex offender from Wisconsin and a parole violator, court officials said at a hearing Saturday.

Kurtis Mcvae entered Manhattan Criminal Court with a scruffy beard and mustache, and a mop of dirty blonde hair. 

The 36-year-old’s hands appeared dirty and he was wearing a white T-shirt, green flannel jacket with a grey hoodie, forest green sweatpants and grey sneakers.

Mcvae allegedly took the octogenarian’s walking stick after grabbing her arm when she was on her way to Target on Union Square East around 3 p.m. Thursday, cops said.

But the victim refused to let go of her cane, and eventually fell in the struggle, Assistant District Attorney Sydney Albert charged in court. She was taken to the hospital in stable condition and released.

The victim’s health aide took a photo of Mcvae’s clothes, which was used to create a wanted poster and led to his capture, Albert said.

Mcvae has failed to appear in court three times in other cases, prosecutors said.

He is a registered sex offender in Wisconsin and failed to register the status in New York, Judge Felicia Mennin said.

Also in New York, Mcvae has had six prior arrests — on charges including petit larceny and possession of a controlled substance, police sources have said.

He is also a probation and parole violator in New York, the judge said. 

Defense attorney David Park acknowledged that “the allegations sound serious,” but said his client does not have the resources to post bail or to flee. 

Mcvae has worked as a stocker at Macy’s on 34th St. for seven months and lives in a Bowery shelter, Park said. Before working at Macy’s, Mcvae was “recycling plastic,” Park said. 

Mcvae addressed the court several times about his employment, muttering incoherently. 

His lawyer said McVae had missed court dates because he “misplaced the paperwork.”

Mcvae said he missed a Feb. 17 court date for a robbery arrest at Duane Reed because he was working “from 9:30 in the morning to 4:30 in the afternoon.”

Judge Mennin set his bail at $7,500 cash, $30,000 bond, and $25,000 insurance company bond. He was sent to Rikers Island.

Reached at home, the victim told The Post she was “better now,” but declined to comment further.
