Eleven arrests have been made in connection with a suspected gangland clash at Lawkholme, Keighley, police confirmed this week.

Most of the arrests were in relation to alleged disorder, assault and robbery offences.

All those arrested -- who are young men from the Keighley and Bradford areas -- have been released on police bail.

Detectives investigating the August 22 incident -- in which shots were fired -- have also seized various items of clothing and other articles, which have been sent for forensic tests.

Firearm cartridges recovered at the scene are also being examined. But police say that despite the arrests -- and more are expected shortly -- they are disappointed with the public response to appeals for information.

Det Insp Trevor Gasson, who is heading the investigation, code-named Operation Penzance, said: "We have had meetings with community leaders and are continuing to carry out house to house inquiries in the area, but we have had very little information so far from the public.

"We need independent evidence, and I would appeal once again for anyone who has information which may be of help to the inquiry to come forward.

"None of those arrested have been charged as yet. We will be liaising with the Crown Prosecution Service."

Parts of Lawkholme were turned into a battleground when a car chase ended in Parson Street and a brawl left a trail of damage, including five wrecked cars and smashed bollards. Three people were taken to hospital.

The following day two men were assaulted, one seriously, on an industrial estate just yards from the scene of the original attack.

Anyone with information is asked to contact the incident room at Keighley Police Station on 01535 617167.

Police from Bradford were drafted in to help deal with the incident, which was believed to revolve around a long-running drugs-linked dispute between two Asian gangs.

A 25-strong Bradford gang in cars chased a Lawkholme vehicle back to its home territory and then smashed up a parked BMW.

Shots are believed to have been fired and a pitched battle followed in Parson Street between the two groups.

When police arrived they found dozens of residents on the streets and cars speeding in circles at the junction with Lawkholme Lane.

Det Insp Gasson said this week that over 100 homes were still to be visited by officers carrying out house to house inquiries.
