Counter-terrorism police have been brought in to help investigate the murder of a Rochdale Iman following the discovery of materials linked to the Islamic State (IS), reports the Manchester Evening News. Jalal Uddin died after being found with serious head injuries at a play area in Wardleworth on 18 February.

Police stepped up their investigation after they discovered material related to terrorist group following a series of raids in the Greater Manchester area. The material includes digital media thought to have been found on computers or smart phones, the newspaper said.

Uddin, a former Imam at the Jalalia Jaame Mosque on Trafalgar Street, Rochdale, is reported to have urged youngsters in the area against joining IS.

A Greater Manchester Police spokesperson said: "The investigation into the murder of Jalal Uddin is now being led by the North West Counter Terrorism Unit (NWCTU) in cooperation with officers from the Greater Manchester Police Serious Crime Division.

"While the investigation is yet to establish a firm motive for the murder, the NWCTU are better placed to provide the expertise necessary to successfully investigate this crime and any associated offences.

"The investigation team continues to remain open as to the reasons why this tragic incident occurred but we are continuously reviewing the evidence to establish whether this killing was motivated by hate or religious extremism."

Mohammed Hussain Syeedy, 21, of Ramsay Street, Rochdale, has been charged with murder and conspiracy to commit murder. Two other males, aged 17 and 21, have also been arrested in connection with the attack. They are currently on bail pending further enquiries.
