Cllr Claire Kober OBE, Chair of London Councils, said:
“Last night’s attack on young people and families enjoying an evening out has shocked us to the core. Today we remember those who have tragically lost their lives and all our hearts goes out to the people of Manchester and all those families and communities affected by this senseless attack.
“I know many London residents will be concerned as they go about their day, but they should not be fearful. I am, however, urging everyone to remain vigilant and report anything unusual.”
Anyone with concerns should call 0800 789 321. In an emergency always call 999.
