Naked man jumps on house roof

Police say the man is jumping from roof to roof

Police have cordoned off a terraced street after a naked man climbed from a window on to the roof of a house.

Officers were called to the house after reports that a man had been seen armed with knives.

The siege in Greyswood Street in Wandsworth, south London, began at about 1350 BST on Thursday.

Police said the man was naked and had been jumping from roof to roof. A negotiator is at the scene talking to him.

When officers arrived three people made their own way out of the address unharmed.

One man - who is estimated to be aged in his mid-40s - climbed from the first floor window on to the roof.

A Metropolitan Police spokeswoman said: "It is fairly low level at the moment. We are continuing to talk with him."
