THE father of Rhys Jones’s killer will not be charged after being arrested over an arson attack on the home of his son’s fellow gang member, Gary Kays.

Joseph McCormick, 56, was detained by Merseyside Police in July after the home Kays shared with his family in Croxteth Park was set alight.

McCormick, whose murderer son Sean Mercer, 18, was locked up for life last year, was questioned and then released on bail yesterday.

A spokesperson said: “No further action will be taken as there is no evidence to support action against him.”

A petrol bomb was thrown through a downstairs window of the property on Mallard Close in the early hours of Saturday, July 11.

Businessman Gary Kays senior and his wife, Patricia, were on holiday at the time, but their daughter was at home.

She and her boyfriend managed to extinguish the fire.

Kays junior, 26, was jailed for seven years last December.

He was unanimously convicted of two counts of assisting an offender.

As well as helping to ferry Mercer to an industrial lock-up where gunshot residue was washed off him and his clothes burned, Kays was responsible for putting Mercer at the murder scene.

He phoned his fellow Croxteth Crew gang member to tell him Norris Green thugs were on their turf.
