Mental health manager Dan Lynch, 33, saw the tactical unit race into Thenford Street at about 5.10pm.

He said: "I saw all the armed response teams, everyone had machine guns. They were shouting 'armed police' into each of the houses.

"They must have been outside for five or 10 minutes before they went into the house. All I saw was them by the doorway, I didn't see them go in.

"There must have been 16 police officers and they had a man in handcuffs."

Police have confirmed to the Chron that the operation was in response to an alleged attack using a noxious substance. They stressed the substance was not acid, however.

Firefighters were also called to the scene to assist with large volumes of water in the event of a substance being used.
