Army bomb disposal teams worked through the night to prepare for the removal of a Second World War device discovered on a building site.

Schools and properties were evacuated on Thursday after the unexploded bomb was found in north-west London, forcing local residents to take shelter in a church overnight.

However, the evacuation area was increased overnight with hundreds of people facing being away from their homes for the weekend.
