Merseyside actor Stephen Graham was today spotted filming in the city centre for what is believed to be a drama about the 2007

murder of schoolboy Rhys Jones.

Stephen and a host of actors and extras were seen in costume outside Liverpool Crown Court on Sunday afternoon.

Crews had previously been spotted filming in a pub in Astely, Wigan, for ITV鈥檚 four part drama.

The Wigan pub was being used as a stand in for the Fir Tree Pub in Croxteth - the pub schoolboy Rhys was shot dead outside of in August 2007 as he walked home from football practice.

Liverpool actor Stephen Graham, who has also appeared in Boardwalk Empire and This is England, has been cast as SIO Dave Kelly, who led the investigation into Rhys鈥檚 murder on behalf of Merseyside Police.

The innocent 11-year-old was the tragic victim of gang violence as a hooded teenager who was aiming at members of a rival mob fired from a mountain bike.

Rhys was hit in the back as shots were fired across the pub鈥檚 car park and died in his mother鈥檚 arms.
