Two men were arrested on suspicion of robbery near Bermondsey Tube Station on Wednesday May 4.
An MPS Helicopter was used to help locate suspects on a moped in Rotherhithe New Road, before following them to Bush Road, Rotherhithe.
Alex Sergei, of Surrey Quays Food and Wine on Bush Road, said: “At about 2pm there was a police helicopter and six or seven police cars and vans outside my shop.”
The two suspects are now on bail pending further investigations.
