Today there's a stronger than normal police presence on the High Street, aimed at reassuring local residents and businesses. Last night many of them were forced to take shelter.
Charles, who works at Tapi Carpets and Floors on Clapham High Street, told me a pregnant woman and her husband were forced to take shelter in his shop when hundreds of teens were rushing towards them.
"She was panicking, she was really, really panicked. Her husband was having to calm her down", he said. Charles locked the door of his shop while they took shelter for a quarter of an hour.
But Charles tells me he's worried that more of these gatherings could take place.
This is the second one this week. The first happened on Saturday, when teens stormed M&S.
