Theft Description

Parked the bicycle by  Shirley High St, Nationawide Bank, bicycle lock place, there was a group of boys and girls (about 6, dressed like roadman)standing  behind Bright House/Cash Generator buildings where there was a Blue car parked there(i think a Honda as it had H) they were looking into the car moving around it as me and my son were locking our bikes.We sort of observed them a bit as, to what they wanted to do on the blue car but we left to the big Poundland next to Boots. We spent about 20 minutes at Poundland, as we came back to the bicycle Lock place we saw that the lock was cut and my son's  Voodoo bike was gone only my bicycle was there with the brocken lock. we looked around in disbelief, confused, and asked people who were about if they have witnessed anyone taking my son's bike, one said he saw the group that was standing by the blue car surrounding my son's bike,then cutting off the lock and all of them running away with one of the boys taking off with the bike.we didn't even take the details of anyone as we were just gutted of the incident.we walked around asking if anyone have seen the bike and my son called 101 and was advised to report online.
