Marks and Spencer retail boss warns crime is getting 'more brazen' after days of unrest

Marks and Spencer's retail boss has warned crime is getting "more brazen, more organised and more aggressive" after a week plagued by antisocial behaviour.

Retail director Thinus Keeve hit out at the government and London Mayor Sadiq Khan in a letter posted to the supermarket's website on Thursday.

"Without a government seriously cracking down on crime and a Mayor that prioritises effective policing, we are powerless," he said.

After the unrest on Saturday, about 100 officers responded to antisocial behaviour in Clapham, south London, on Tuesday, four of whom were assaulted, along with one member of the public.

Scores of teenagers and young adults were participating in so-called "link-ups" - using social media apps including TikTok and Snapchat before surging into shops.

Marks and Spencer was reportedly one of the stores targeted.

Mr Keeve went on: "It is becoming more brazen, more organised and more aggressive."

"We need a stronger, faster and more consistent police response, using tools that already exist to target repeat offenders and crime hotspots," he said, adding: "It's a clear ask: support our police. Help them show up in our communities when and where we need them.

"Give them the resources they need to tackle crime effectively, and ensure they work with retailers to consistently use the tools we've developed to share data and actively target offenders."

He also questioned claims that crime rates are falling in the capital.

He said: "I keep hearing crime is falling, especially in London - something none of us believe, and very few people working in retail would see."

M&S chief executive Stuart Machin has written to the Home Secretary Shabana Mahmood following the scenes over the weekend.

Sir Sadiq condemned the scenes as "utterly unacceptable".

The London mayor said "the culprits will face the full force of the law" and police were working with social media companies to try to clamp down on "viral online content which promotes violence and theft".

Meanwhile, police in Rochdale issued a 48-hour dispersal order following anti-social behaviour.
