Prison bosses confirmed to the ECHO the Liverpool man was attacked on January 10.
A Prison Service spokesperson said: “The incident has been referred to police. It would be inappropriate to comment further."
The ECHO understands Caswell was treated by healthcare staff internally for a cut to the neck. He did not require hospital treatment.
Caswell has been on remand at Strangeways prison since he was charged with a number of serious offences in 2020. Caswell entered guilty pleas last November.
Caswell, known as 'Will Young' in criminal circles due to his similar appearance to the pop star, was jailed for 17 years in 2005 for his part in a series of car bombings across the city.
The former nightclub doorman became embroiled in a dispute between a group of violent drug dealers and the owners of city centre nightclub 051.
Caswell targeted the home of one of the owners , setting off a massive blast on Sandfield Walk, Sandfield Park, West Derby in October 2003.
The next day he targeted the home of a woman who was linked to the same family.
On May 13, 2004 Caswell set off a car bomb outside West Derby Road police station in Tuebrook.
The bombing campaign generated huge concern at the time and led to a massive police operation to target Caswell and his associates from Kirkdale and Everton.
At one point police targeting the gang were advised to wear bullet proof vests while off-duty in case they were identified by dangerous criminals.
The ECHO understands Caswell was a junior member of a gang controlled by Mark Richardson and David Hibbs Turner. The two well known north Liverpool criminals are now serving life sentences for murder.
Some of Caswell's associates later tried to free him from Walton jail with a hydraulic cherry picker, but prison staff rumbled the plot.
Judge John Roberts, who jailed Caswell for 17 years in 2005, said: "Innocent bystanders could have been killed or mutilated by those bombs. They were offences against the community."
In 2011 Hull Crown Court heard how Caswell attacked another prisoner at HMP Full Sutton prison. Caswell punched Wayne Walters during a fracas in the prison kitchen. A jury found Caswell guilty of actual bodily harm and he was handed an extra ten months.
Caswell pleaded guilty to conspiracy to supply heroin, cocaine, conspiracy to possess criminal property and conspiracy to commit robbery. He entered the pleas on November 10 last year and will be sentenced later this year.
