Child killer Jon Venables was secretly quizzed by police just weeks after he was freed from prison.
Venables, 35, who was released from his prison sentence for killing two-year-old James Bulger in Liverpool in 1993, was hauled before police in 2001 for a public order offence.
The allegations, which were made while he was under police protection, were never made public and it is unclear if further action was taken.
It also emerged that in 2003, he reportedly tried to sue the police for wrongful arrest and false imprisonment.

Sources close to the case told The Sun that Bulger’s family were not told about the arrest, sparking fears it may have been covered up by officials despite his police protection costing the taxpayer £23,000 a month.
The source told the newspaper: ‘Huge amounts of time and public money were lavished upon him. Was the public ever being told the truth about how its money was being spent?’
At the weekend it emerged that Venables is is planning to marry and have children with a woman who knows all about his horrific crimes when he leaves prison.
His bride-to-be is fully aware that he murdered two-year-old James Bulger and has even been showing off her engagement ring after he proposed last year.
When Venables was jailed for 40 months for downloading child porn in recent weeks, the fiancée still stood by him.
A source told The Sun Online: ‘Officials have made this woman fully aware of Venables’ horrific crimes yet this hasn’t stopped her wanting to be with him.
‘You have to question what kind of woman would choose to spend their life with a convicted child killer and paedophile.’
They added that while the couple are planning a happy life together, James had any chance of finding his soulmate snatched from him when he was killed.

Venables was forced to reveal his identity to his girlfriend when officials realised how serious the relationship was.
He told her how he and Robert Thompson murdered the two-year-old after abducting him in Liverpool in 1993.
Both were released on licence from a young offenders’ institution in 2001 when they turned 18.
Now Venables and his girlfriend have been chatting about starting a family.
‘They are an item,’ a source told Daily Star Online.
‘They were talking about having kids together. They spoke about it quite a lot.’
A prison source told the Daily Star that Venables had ‘blurted out’ his plans to have children to a prison officer when giving reasons ‘why he wanted to live’.
Venables was living with his girlfriend when probation workers found a laptop hidden behind a headboard in his room.
They discovered 1,160 child abuse images and videos. The Old Bailey was told that almost 400 fell in the most depraved category.
He was also found to have downloaded a manual on how to abuse children. There is no suggestion his partner knew what he was using the laptop for.
Though his girlfriend is childless, she has relatives with primary school age youngsters.
News of the engagement comes as a fresh investigation launches into leaked photographs of Venables, Mirror Online reports.

Prisoners are understood to have obtained pictures that reveal the killer’s identity. The images are said to reveal his alleged new name.
They reportedly identify the prison in which he is serving his sentence for indecent images of children.
Branding him a ‘dirty nonce’, the inmates say they want to ‘expose’ Venables.
But if they did that they would risk two years in jail for breaching the anonymity order that protects Venables and Thompson. Both were aged 10 years old when they abducted James in Bootle.
The Attorney General’s office said: ‘We have received complaints the anonymity has been breached. An investigation is ongoing.’
There are fears harm could befall Venables or innocents wrongly identified as the killer.
It is thought he has been given as many as four new identities, with each reportedly costing £250,000.
