Man arrested on suspicion of theft of Banksy street sign in London

Artwork, potentially worth up to 500,000, was stolen an hour after it was confirmed as genuine

Detectives arrested a man last night on suspicion of the theft of a Banksy street sign worth up to 500,000 that was stolen in London less than an hour after being confirmed as a genuine installation.

The Metropolitan police said they had deployed detectives to investigate after a council in south-east London asked them to help find the stolen artwork. The piece - a red stop sign with three military drones on it - appeared on the corner of Commercial Way, Peckham, on Friday morning - with Banksy confirming its credentials just after midday.
