A lengthy lockdown in a northeast London neighbourhood was lifted late Sunday afternoon.
Police descended on Cecilia Avenue Sunday morning and surrounded a home for most of the day, with heavily-armed tactical officers.
Residents were prohibited from coming and going and crowds of onlookers gathered along side streets to watch the drama unfold.
Police entered the home around 4:30 p.m. but returned a short time later. No suspects were seen.
The fire department arrived soon after to ventilate the home.
Police are tight-lipped about the lengthy lockdown.
