Detectives hunting the killer of a postman attacked delivering letters on his early morning round are renewing their appeal for information six months after his death.
Postman Paul Savage died in hospital
Paul Savage, 30, died in hospital in February after he was assaulted as he delivered the mail in Mold.
Despite a detailed reconstruction, Royal Mail's £25,000 award and intensive efforts by police to trace the killer, the murderer is still at large.
On Monday Detective Superintendent Chris Corcoran said the investigations so far had led to 19 people being arrested, three firearms found and over £30,000 of Class A and B drugs being seized.
In July a blue hooded top believed to have blood on it was found on an area of wasteland behind Ivy Crescent in the Queen's Park area.
Police are still awaiting forensic results on the clothing.
Police stage a reconstruction of the attack
It was on 4 February that Mr Savage, originally from Sale, Greater Manchester but the living at Gwernaffield, was attacked as he delivered letters near Mold school.
The postman suffered a fractured skull after he was hit about seven times with a wooden club. He died later in hospital.
His bicycle and mail bag were left nearby, and police have said nothing was stolen in the assault.
Two hooded men were spotted running away from the murder scene past some shops, but they have never been traced.
After Mr Savage's death, it was revealed that he had a number of criminal convictions.
