DETECTIVES have released images of two men they are keen to speak to in connection with three linked violent incidents in Hillingdon in August, one of which left a man unconscious.

A man at a house party on Hindhead Road in Uxbridge was bitten on the lip and punched so hard in the face he had teeth knocked out, at about 2.10am on Saturday August 22.

In a second altercation, a man sustained a fractured eye socket, at the Ivy Leaf Club on Wellington Road, Uxbridge, at about 10pm on Friday August 28.

Fifteen minutes later in the night, a man was beaten and kicked in the head and body to the point of unconsciousness by a number of men at the Grand Union on High Street, Cowley.

A group of people fled as police and the London Ambulance Service arrived on scene. Police said all of the individuals were known to each other.

Officers are keen to trace and speak to Daniel Hingerton, 25, who they say is known to have links to Hillingdon, Perivale and Northolt.

A second man - yet to be identified by police - is described as white, in his 40s or 50s, of medium build and with a distinctive receding hair line at the sides.

Detective Inspector Andrew Smith, of Hillingdon CID, said: "We are asking the public to look closely at the images and help us to identify the whereabouts of these two men.

"Our appeals are an extension of a large scale investigation which has already resulted in the arrest of a number of individuals along with one charge.

“This fast moving enquiry continues to gather momentum and forms part of our long term commitment to bringing violent offenders to justice."

Yesterday officers at Hillingdon CID, with support from the MPS Territorial Support Group, carried out six search warrants at addresses in Northolt, Uxbridge, Ealing, Chiswick, Slough and Beaconsfield.

Four men, aged 47, 46, 41 and 27, were arrested in connection with the investigation and were held in custody pending further enquiries.

Police said they recovered class A drugs and a stun gun at the addresses, along with a quantity of cash seized under the Police and Criminal Evidence Act.

On September 1 a 27-year-old man handed himself into police in connection with the investigation and was subsequently charged with grievous bodily harm.

Anyone who knows of the whereabouts of either men can call police on 101.
