A SECOND teenager has been arrested on suspicion of robbery in connection with a man who was found collapsed in Altrincham.

The 16-year-old boy from Broadheath was arrested today (May 8) and has been bailed until 19 June 2008 pending further inquiries after David O'Kell, known locally as Market Dave, was found unconscious in mysterious circumstances.

Earlier today police confirmed confirmed that Mr O'Kells' condition had improved.

Mr O'Kell is now stable but because of his age police said it will be a long process before he is able to make a full recovery.

Another 16-year-old boy was arrested on suspicion of robbery on April 20 and has also been bailed until June 19.

At about 11.10pm on Wednesday April 9, police were informed that a passer-by who was walking along Huxley Street near Homebase had found Mr O'Kell, 67, lying in the bushes.

Officers attended and he was taken to Wythenshawe Hospital with a head injury. He was later transferred to Hope Hospital where he remains in a serious but stable condition.

Inquiries later established that Mr O'Kell had been drinking in the Railway pub in Broadheath earlier on.

He is unable to tell police how he sustained his injuries and police are continuing to try and trace anyone who may have seen him at about the time he collapsed to establish what happened.

In particular, officers want to speak to three youths who were seen running along Princess Street from the direction of Huxley Street at about 11.00pm.

Detective Sergeant Andy Reynolds, from Trafford CID, said: "At this stage, we still do not know what happened or how the victim sustained his injuries. There were no witnesses or CCTV and there remains some mystery as to exactly what did happen.

"We still want to hear from these youths because they could be valuable witnesses and they may be able to help piece together what happened that night.

"The victim has suffered quite a serious head injury and we are anxious to know what happened. I would appeal to anyone who can help to come forward."
