A man is under arrest after a Facebook page was set up lauding suspected police officer double killer Dale Cregan as a "legend".
The "tribute" went online within hours of PCs Nicola Hughes, 23, and Fiona Bone, 32, dying in a gun and grenade attack in Hattersley, Tameside, on Tuesday morning.
Greater Manchester Police announced the arrest as officers continued to question Cregan, 29, on suspicion of murder.
He was detained after walking into a nearby police station after the attack.
