Christine said she was walking with her husband and baby in Clapham High Street when she saw hundreds of young people, adding: “I think it took everyone by surprise.”
She continued: “We weren’t sure what was going on initially. There were a lot of police and police cars. You don’t see that very often, even having such a heavy police presence was very unusual.
“It was clearly people up to no good. It was quite intimidating, especially with a new baby.”
She added: “It’s a great neighbourhood, I’m sure it’s just a one off. The police were very good yesterday, it was reassuring to have so many around.”
