Officers in Wandsworth executed one of 21 warrants and a further 18 arrests across the capital today (August 22) in the lead-up to Nottingham Hill Carnival.

Forming part of the Met's pan-London response to violence and knife crime, police have been engaged in proactive operations since Friday, August 11, which target and disrupt gang crime, drug supply, knife crime and other offences.

It aims to tackle threats to safety which may occur at Notting Hill Carnival this weekend (August 26 - 28).

Prior to this morning's activity at 4am, officers have made more than 290 arrests for a range of offences and recovered 190 knives and 18 firearms.

This activity will continue during the week and include weapon sweeps, stop and searches, youth engagement and ANPR operations.

Other boroughs involved in the two intelligence-led operations include Kensington and Chelsea, Westminster, Hammersmith and Fulham and Lewisham.

Officers in Lewisham executed eight warrants and arrested eight people, seizing what is believed to be class A and class B drugs.

The borough officers were assisted by the territorial support group, safer neighbourhoods teams and the dog unit, as well as colleagues from the City of London police and British Transport Police.

The arrests are predominantly for possession with intent to supply drugs, and some of those arrested may be bailed pending further enquiries but will have bail conditions imposed on them that prohibit their attendance to the carnival.

Highly-skilled officers, known as 'super recognisers', will be there and in the CCTV control room over the weekend, looking for anyone banned from the event.

Chief superintendent Robyn Williams, the Met's spokesperson for Notting Hill Carnival, said: "Our officers have been proactive and focused on tackling serious violence and knife crime across London. Today's operation is aimed at ensuring that those who intend to cause trouble at the carnival are prohibited from doing so.

"We are committed to ensuring that the carnival remains a safe, vibrant and enjoyable event; troublemakers are not welcome. We will be uncompromising in our operations to keep our communities safe and secure. People can expect to see operational activity right up until, and throughout the bank holiday weekend."

If you know anyone who is planning to use Notting Hill Carnival to commit crime, please call Crimestoppers anonymously on 0800 555 111 to help the Met keep the event a safe celebration.

Robyn added: "We have been planning for the carnival for some time, and working closely with the organisers and our partners. Officers will be on duty throughout the weekend to keep people safe. We want you to enjoy the weekend, but if you are concerned or see anything suspicious report it to an officer.

"Basic advice to those coming is to look after your belongings, and in particular, keep an eye on your mobile phone."
