Police are hunting two men in connection with a series of savage attacks within the space of six days.
Three people were seriously injured after the attacks in August, during one of which a man was beaten, kicked and stamped on until he lost consciousness.
Detectives today named 25-year-old Daniel Hingerton as someone they are keen to trace over the attacks. A second unnamed man is also sought.
Four men were arrested today after search warrants were executed at six addresses across west London. Class A drugs and a stun gun, as well as a quantity of cash, were seized during the raids.
Police said the first of the three attacks happened just after 2am on Saturday, August 22, when “a number of men” were involved in a fight at a house party in Uxbridge. One man received a bite wound to his lip and had his teeth knocked out by a punch during the incident in Hindhead Road.
In another attack six days later a man suffered a fractured eye socket and another was also injured during an altercation at the Ivy Leaf Club in Wellington Road, Uxbridge, according to detectives.
Fifteen minutes later a man was knocked out by a group of men at the Grand Union pub on the high street in Cowley, police said.
Scotland Yard said a number of people – all of whom are known to each other – fled when police were called.
Detective Inspector Andrew Smith of Hillingdon CID said today: "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."
A 27-year-old man has been charged with GBH after handing himself into police on September 27.
