A 31-year-old man arrested on suspicion or murdering a prominent member of a Greater Manchester mosque has been released without charge.
Greater Manchester Police said the man had been “eliminated” from its investigation.
The victim, found with a head injury on Thursday in a play area in Rochdale, has not yet been formally identified.
A Facebook post on Friday from Jalalia Jaamé Mosque said Koran reader Jalal Uddin “passed away last night”.
It is understood Mr Uddin was a qari (Koran reader) at the mosque. He is believed to have been on his way home from a friend’s house when he was assaulted between 20:40 GMT and 20:55 GMT.
