The man arrested in Wigan yesterday in connection with the Manchester attack had been staying at an address near the town centre, Wigan Today understands.
Police raided the address on Springfield Street in Swinley in the early hours of Thursday.
The man was not the registered tenant but had been staying at the location for an unspecified period of time.
Residents of the other flats at the premises have now been allowed back into their rooms.
But a police presence remains on the street and the flat in question remains under guard.
One resident speaking about the early hours raid said: “I was watching TV and I heard some loud noises from my neighbour’s and then there were lights everywhere outside.

“I opened the door because I was surprised what was going on and a police man said to me go back in, everything is okay.
“But outside there were around about 10 officers.”
Another resident said he saw an officer with a gun outside at around 1.30am.
Police vans were also sent to the scene and were spotted by a veterinary practice’s employees arriving for work at around 8am.
At 9am two officers were standing guard on the front doorstep of an address on the quiet residential street.
