A gunman robbed a worker at the Biscuit Factory in Bermondsey last month, and fled on a mate’s moped.
A Met Police spokesperson confirmed the force was called on August 16 to reports of the gunpoint robbery at 3.05pm.
The male victim’s bag was stolen, though he was not hurt in the attack.
The suspect and moped driver are still at large, and no arrests have been made.
Anyone with information that could help the police should call 101 to assist with their ongoing enquiries.
The News understands that a team of six officers carried out an arrest on August 24, at the same location next to Drummond Road.
A male who had been driving a moped was apprehended and questioned at the scene at about 10.30am. He was then released shortly afterwards.
Police were unable to confirm that the two incidents were connected.
