A heavy police presence was seen on a Bolton street today, June 2.
Four force vehicles were seen on George's Lane in Horwich at around 10.30am today.
Officers were said to not be letting anyone up the road, although they were letting people out of it onto Chorley Old Road.
Multiple eyewitnesses have said that "armed police" were present, but GMP have not confirmed this.
Officers were not said to be on scene for long, only around "half an hour".
One resident said: "We saw officers blocking off George's Lane. My wife said she heard a bang that sounded like a gun this morning, it sounded like it was off in the distance.
"There is the quarry up there, but we don't usually hear bangs from the quarry.

He added: "It didn't last very long, around half an hour or so."
