OPP took one person into custody following a standoff in east London on Saturday morning.
London police officers blocked off Cleveland Ave. and residents around Barberry Court were asked to stay indoors.
A supervisor on scene told CTV News they were conducting an active investigation and due to potential danger, no media, pedestrians, or cars were permitted to pass between Vinewood Court and Kimberley Avenue.

According to a neighbour who spoke to CTV News anonymously, the OPP tactical team was on site with riot gear and LPS used a loudspeaker asking a resident of Barberry Ct. to come outside.
They say police also asked people to go into their basement and take cover.
He told CTV News that two men exited house number 15 and police confirmed on person was arrested.
The neighbour added that he’s been a resident of the area for 10 years, and this is not the first time police have been to the residence.
OPP say charges are pending.
