Michael joined the Metropolitan Police Service in 1982 working in a number of London Boroughs in both uniform and criminal investigations. On promotion to Superintendent he worked for TPHQ (Territorial Policing HQ) in a variety of crime roles, heading up the National Mobile Phone Crime Unit, Led the MPS TP strategy for Proceeds of crime, and the London Crime Squad tackling Cross border and Organised Crime Groups.

He joined the London borough of Wandsworth in 2008 to tackle a significant rise in gang violence driven by drugs and night time economy, implementing a strategy to tackle gang members utilising proactive, reactive and partnership resource. He introduced a matrix for scoring risk and harm and worked with the partners to target appropriate activity to engage the most harmful and vulnerable people. The borough recorded a significant decrease in violent and acquisitive crime.

He was appointed Head of Crime, Policy and Performance for TP in 2010 with responsibility for Pan London Pro activity, Performance data, National crime registrar / incident lead and Pan London public protection including dangerous offenders and safeguarding children and adults.

He implemented Operation Connect, the MPS response to growing gang related violence, and is heavily involved in establishing funding to support activity in diversion, training and enforcement to ensure continuity and resilience.

In November 2011, Mick was asked to lead the Ending Gang and Youth Violence team, offering support to 30 local authority areas in England. The EGYV team is set up to help areas:

 Map the different agencies which may be in contact with gang nominals and their families;
 Map the local gang or serious youth violence problem, using partnership data;
 Review their procedures for identifying gang members and potential victims;
 Gather independent feedback from local communities on what could be done better;
 Scrutinise prevention and enforcement strategies and suggest areas for improvement;
 Agree a practical action plan to improve the way gangs are tackled locally.

This is part of the cross-government drive to tackle youth and gang violence outlined in the Home Office report” Ending Gang and Youth Violence”, report published in November 2012.
