Burglars got away with around 60 mobile phones, 10 digital cameras, accessories and cash from a Goodmayes shop over the weekend.
The owner of E-Zee Communications, in Ravening Parade, Goodmayes Road, discovered the theft when he went to open up on Monday morning.
Police believe the shop was raided between closing at 9pm on Saturday and 10am on Monday.
The burglars had got in through a rear door.
Investigating officer Det Sgt Dave Bonnyhood, of Ilford Burglary Squad, said: “I appeal to anyone who was in the area at the time of the incident and may have heard or seen anything suspicious, or anyone that may have been offered a mobile phone to contact me.”
Anyone with information is asked to call DS Dave Bonnyhood at Ilford Police Station on 0208 345 2680 or Crimestoppers anonymously on 0800 555 111.
