DETECTIVES investigating a shooting that left a Southampton man in hospital have today made a fourth arrest.

A 38-year-old man from Southampton was detained by Hampshire’s Major Investigation Team in the early hours of this morning on suspicion of attempted murder.

As reported, police have also already arrested two 25-year-old men – one from Southampton, one from London – on suspicion of attempted murder in connection with the shooting in Townhill Park on Sunday evening.

Armed police descended on Vanguard Road at 7.15pm after a 27-year-old collapsed at a Tesco Express store in Cobden Avenue.

He is still recovering in Southampton General Hospital after undergoing surgery on non-life threatening injuries to his legs.

Police are still hunting for the weapon, believed to be a handgun, that was used in the attack.

Detectives yesterday also arrested a 15-year-old Southampton boy on suspicion of a firearms offence in connection with the shooting.

He was last night released on police bail until March 6.

The 25-year-old Southampton man was arrested on Sunday evening and later released after questioning. He is due to report back to police today.

The London man was arrested yesterday morning outside of Hampshire, and was brought to the county to be quizzed by detectives.

He was still in police custody this morning.

A team of around 40 officers is working on the investigation, codenamed Operation Saddlewood.

An area around several blocks of flats between Witts Hill, Vanguard Road and Lytham Road is still cordoned off as police hunt for potential forensic clues to the shooting.

Police have again thanked residents living in the affected area for their patience and co-operation, and have vowed to lift the cordon “at the earliest opportunity”.

They have also repeated their appeal for any potential witnesses to the shooting to come forward.

Anyone with information should call Hampshire police on 101 or Crimestoppers anonymously on 0800 555 111.
