BJ moved then to the first of a number of postings to the Territorial Support Group (TSG), working at Caledonian Road and then North Finchley bases. In this role he developed his interest in public order and event policing, as well as gaining policing experience across London in both uniform and plain clothes.

On promotion to sergeant in 1996, BJ moved to Tottenham Division, firstly leading a uniform team and then specialising as neighbourhood team sergeant for Tottenham High Road and the Broadwater Farm Estate. Through this period he gained an important understanding of the critical role of community policing, both in building community confidence as well as fighting crime.

Within this period he was promoted to inspector and ran one of the TSG units, finishing up as the acting chief inspector.

He developed key multi-agency partnerships and joint tasking across a range of issues, including licensing, crime prevention and drug and alcohol intervention.

Whilst at Lewisham, BJ also took over leading the Criminal Investigation Department alongside his operations function. This provided him with valuable insight into more complex crime investigations and the opportunity to integrate these often separate areas of work. It was also during this period that he graduated as part of the Cabinet Office Leaders UK senior public service leadership programme.

Leaving Lewisham, BJ moved to become chief superintendent in charge of the Met’s three command and control centres, bringing about significant change and consolidation of new operating systems. He continued as a public order commander at events such as Notting Hill Carnival and, within this, led the MPS-wide review into stop and search.

In this role, working to the Deputy Assistant Commissioner in Specialist Crime and Operations, he led the development and change of Pan London Policing operations and Specialist Crime.

In 2013, he was appointed the Borough Commander for Camden in North London, leading the policing of one of London’s busiest areas with a significant night-time economy and also a very diverse community. Within this role he supported the implementation of the first Safer Neighbourhood Board and the increase of Volunteer Policing Cadets from a handful to over 100 young people.

BJ completed the Strategic Command Course in 2014 and, in October 2014, was promoted to Area Commander for North London. In June 2015 he was given responsibility for public order and operations policing across London.
