Former drug dealer Curtis Warren was arrested on suspicion of breaching his Serious Crime Prevention Order.
The 60-year-old, from Toxteth, was arrested by the National Crime Agency in Boldon Colliery, South Tyneside, just before 6am on Wednesday, July 5. He is being questioned by police on suspicion of committing numerous breaches.
The order came into force after his release from prison in November 2022 for drug trafficking offences, and the suspected breaches under investigation relate to the unauthorised use of mobile phones, vehicles, bank accounts and travel.
