Parts of Kingston have been sealed off since Thursday morning (Picture: Facebook/Kingston Police).
Homes have been evacuated in south-west London after a suspected unexploded Second World War bomb was discovered at a building site.
The device was found on Fassett Road at around 9:15 BST on Thursday.
Police sealed off parts of Kingston upon Thames, including polling stations and two of Kingston University's campuses.
The item has been examined by specialist officers and the assistance of the Ministry of Defence and other emergency services continues to be sought, police have said.
A cordon remains in place, and is expected to be there until at least 16:00 BST on Friday.
People taking part in Thursday's European elections were instead directed to other sites to cast their vote.
Police patrols are continuing, and officers have asked for the local community to follow them on Twitter at either @MPSKingston or @metpoliceuk for updates. Residents affected are requested to call Kingston Council contact line 0208 547 5800.
