He also helped the police to develop the first-generation Major Incident and Disaster Support System.

In 1999, he was seconded to the Interpol General Secretariat in Lyon, France, initially as Liaison Officer. In 2001, he was promoted to assistant director of its Asia and South Pacific Branch.

On 4 May 2015, the State Council of the People's Republic of China appointed Lo Commissioner of Police, succeeding Andy Tsang Wai-hung. He was criticised as "soft" and "feeble" by frontline officers after he announced an investigation into the firing of two warning shots by a police officer during the 2016 Mong Kok civil unrest.

On 15 February 2017, Lo stated that he was "saddened" by the guilty verdict of seven police officers who were found guilty of assaulting the pro-democracy activist Ken Tsang during the Occupy Central protests.

In November 2019, Lo retired as Commissioner of Police amidst criticisms of the police's handling of the 2019–20 Hong Kong protests.

In August 2020, Lo and ten other officials were sanctioned by the United States Department of the Treasury under Executive Order 13936 by President Trump for undermining Hong Kong's autonomy.

On 10 February 2021, Carrie Lam awarded Lo the Chief Executive's Commendation for Government/Public Service for his "significant contribution to combatting the social disturbance in 2019 and safeguarding national security".
