Police Brigadier General Hansel M. Marantan retired from the Philippine National Police (PNP) on 10 July after reaching the mandatory retirement age of 56, ending a career spanning more than three decades marked by high-profile law enforcement operations, legal battles, and a return to senior leadership.

Marantan, an Ilocano and member of the Philippine National Police Academy (PNPA) Kabalikat Class of 1998, concluded his service as regional director of Police Regional Office 4A (Calabarzon), one of the PNP's largest regional commands.

His retirement drew national attention after Interior and Local Government Secretary (DILG) Jonvic Remulla sought a one-year extension of his active service, citing the need to sustain ongoing law enforcement operations in Calabarzon. The request, endorsed by the National Police Commission, was not approved by Malacañang, allowing Marantan to retire as scheduled under the law.

During his career, Marantan held several key operational posts, including assignments with the Criminal Investigation and Detection Group–National Capital Region Field Unit, Davao City Police Office, Peace Process and Development Center, Highway Patrol Group, and Police Regional Office 4A.

While serving in Davao City, he supervised several nationally significant police operations, including the implementation of warrants against former Negros Oriental congressman Arnolfo "Arnie" Teves Jr. He also served as acting Davao City police director during operations involving Kingdom of Jesus Christ founder Apollo Quiboloy.

Marantan's career was also defined by the 6 January 2013 police operation in Atimonan, Quezon, where 13 individuals were killed. Police said the suspects fought back during the operation, while families of those killed and human rights advocates disputed that account. The incident led to criminal and administrative cases against Marantan and several other police officers.

He was dismissed from the police service in 2014 following administrative proceedings but was reinstated in 2017 after the National Police Commission's appellate board reversed the decision.

Marantan also spent more than four years in detention while facing criminal charges arising from the Atimonan operation. After more than a decade of court proceedings, he was acquitted with finality, allowing him to return to active duty and later assume senior command positions, including the leadership of PRO-4A.

The proposed extension of his service generated discussion within law enforcement circles, with supporters citing his operational experience and the years he spent away from active duty before his acquittal, while others maintained that mandatory retirement rules should be applied uniformly.

Marantan officially retired on 10 July after more than 30 years in the police service.
