A man has been filmed stealing a locked bike from a rack in Bristol city centre using bolt cutters.

The alleged theft was filmed by an anonymous man and posted on Facebook where it has been watched by more than half a million people.

He said he was shocked at how brazen the apparent theft was and added "the majority of people just walk on by".

Police say they are investigating.

"We can confirm the theft of a bike was reported to us by the victim on Sunday via our website and investigations are under way," police said.
