Detectives from the Flying Squad have released CCTV footage of three men they would like to speak to in connection with a commercial robbery in Barking.
On Tuesday, 27 December police were called shortly before 18:40hrs to a robbery at Turquoise jewellers, London Road, Barking. Jewellery worth over £50,000 was taken.
Officers attended and found the manager, a 45-year-old man, suffering from head and facial injuries.
The London Ambulance Service were called and he was taken to an east London hospital for treatment to his injuries - these are not life threatening injuries.
Following enquiries officers established that two men had entered the location offering jewellery for sale.
Having observed the jewellery the manager declined and as a result was assaulted.
He was punched several times in the face and over the head, before being tied up. The two men then emptied the shop and contents in the safe.
A third suspect stood outside the shop as a lookout on his mobile phone and then entered the shop and left soon after with the other two suspects carrying bags laden with the shop's contents.
The suspects are described as:
Suspect 1 is described as a white man with a black beard wearing a grey bobble hat, dark blue jacket with a tartan hessian laundry bag over his shoulder, dark trousers and black trainers.
Suspect 2 is described as a white man with a black beard wearing a dark body warmer over a grey top, a dark bag across his waist, grey jogging bottoms and dark trainers with yellow soles.
Suspect 3 is described as a stocky white man with a beard wearing a grey hooded top, grey trousers and white trainers.
Detective Constable Andy Davenport, from the Flying Squad, said:
