Army bomb disposal teams will work through the morning 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.

The bomb, weighing 500lb (227kg), was discovered buried deep at a site in Brondesbury Park, Brent, where construction workers were preparing to build an apartment block.

In the early hours of Friday morning, experts from the Royal Engineers and Logistics Corps were constructing a blast protection layer around the device.

The structure had to be put in place before they could begin work to make the device safe to move.

According to Brent Council, work on the site is expected to continue until at least Friday afternoon.
