Police have issued images of two people they'd like to speak to in connection with three linked violent incidents which occurred within six days.
The events occurred in August, in Hillingdon, and resulted in three people receiving injuries ranging from a serious eye injury to multiple injuries and unconsciousness induced by simultaneous kicking, stamping and beating to the head and body.
Officers are keen to trace and speak to Daniel Hingerton, 25, who is known to have links to Hillingdon, Perivale and Northolt.
A second man, who is yet to be identified by police, is described as a white man, aged between his early 40s-50s, and of medium build with a distinctive receding hair line at the sides.
On Wednesday (September 30), officers at Hillingdon CID, with support from the MPS Territorial Support Group, executed six search warrants at addresses in Northolt, Uxbridge, Ealing, Chiswick, Slough and Beaconsfield.
Four mean - aged 27, 41, 46, and 47 - were arrested in connection with the investigation and remain in custody pending further enquiries.
A quantity of class A drugs and a stun gun were recovered at the addresses along with a quantity of cash which was seized under the Police and Criminal Evidence Act.
Altercations
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."
The first violent incident occurred at approximately 2.10am on Saturday August 22, when a number of men were involved in an altercation at a house party in Hindhead Road, Uxbridge. One man was injured and received a bite wound to the lip and had teeth knocked out from the force of a punch.
The second incident occurred at approximately 10pm on Friday August 28, at the Ivy Leaf Club in Wellington Road, Uxbridge. An altercation took place between a number of men resulting in one sustaining a fractured eye socket and another man receiving minor injuries.
The final incident occurred 15 minutes later at the Grand Union in High Street, Cowley. A man was beaten, kicked and stamped on to the point of unconsciousness by a number of men, police said.
Officers were called to all incidents and attended with London Ambulance Service. A number of individuals fled upon police arrival.
All of the individuals are known to each other.
On September 1, a 27-year-old man handed himself into police in connection with the investigation and was subsequently charged with GBH.
