A motorist reported seeing a police officer raid an address in Manor Road, Wallington, this morning.
Mark Wass, 39, from Sutton, was driving his daughter to school at around 8am when he saw the officers entering the property.
He said: "I saw a group of them coming out of the church opposite, then they ran across the road towards a house.
"As I drove past I looked in my mirror, and I saw one of them was carrying a red thing to break through people's doors.
"On my way back about 8.30 I saw the door of the house was open. An officer carried out a bag that had 'evidence' written across it."
It is unclear why officers raided the property.
