Magical Law Enforcement Patrol

The Magical Law Enforcement Patrol, also called the Magical Law Enforcement Squad, is a subdivision of the Department of Magical Law Enforcement in the Ministry of Magic, comprised of a team of wizards and witches tasked with general law enforcement.

In the 1920s, it was headed by Bob Ogden. Ogden ventured to Little Hangleton to arrest Morfin Gaunt, who had been using magic against local Muggles. Morfin and his father Marvolo resisted arrest, however, thus Ogden later returned with support and arrested both Gaunts.

Based on this, it can be inferred that the Magical Law Enforcement Patrol deals with low-level legal infractions, such as a minor violation of the Statute of Secrecy.
