A cannabis farm containing around 550 plants was found inside and a man has been arrested on suspicion of cultivating class B drugs. He remains on police custody.
Engineers remained at the scene to make the electricity safe.
Sergeant Nick Forshaw, of GMP’s Wigan district, said: “My neighbourhood officers have acted on intelligence from members of the community to target drug dealing in the area.
“This has been raised as a concern at community meetings to myself and local elected members.
“As promised we are doing our best to bring offenders to justice and take illegal drugs out of circulation.
“We cannot do this without the support of honest members of the public who are prepared to provide information via Crimestoppers or direct to the police.”
Anyone with information regarding drugs or other criminal activity is asked to report it to police by calling 101.
