The Magical Law Enforcement Patrol (formerly known as the Magical Law Enforcement Squad), was 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. Ogden eventually died of natural causes by 1996. It is unknown who his successor was.
Arthur Weasley mentioned to Harry Potter, after the latter's disciplinary hearing in 1995, that the Magical Law Enforcement Patrol would deal with the culprit behind the regurgitating toilets in Bethnal Green, a prediction in which he was sadly mistaken, as Willy Widdershins cut a deal with the Minister to spy on Harry and the members of Dumbledore's Army in order to escape punishment for his own activities.
Like Muggle police patrols, the Magical Law Enforcement Patrol/Squad appeared to be tasked with conventional law enforcement tasks. Other sub-departments of the Department of Magical Law Enforcement, such as the Auror Office, dealt with specialised magical crimes.
Behind the scenes:
- As it have never been formally established what kind of services the Patrol provides, it can be assumed that while it is involved in the arrest of less dangerous criminals such as Mundungus Fletcher suspected of petty theft, they primarily serves the entire Department of Magical Law Enforcement as a generic task force which takes its assignments from various its many divisions, such as carrying out house raids on behalf of the Misuse of Muggle Artefacts Office, and while not participating in tracking down Dark Wizards, may help in direct confrontation with them with the goal of apprehending them. It is also possible that the 'Ministry official' who the Improper Use of Magic Office almost sent to destroy Harry Potter's wand before Dumbledore intervened would have been a member of the Patrol, since it is known that they are authorized to carry out arrests, while the Improper Use of Magic Office are only known to issue warning letters.
- Since Hit Wizards/Witches from the Magical Law Enforcement Squad were assigned to arrest Sirius Black when Peter Pettigrew faked his own demise at Black's wand, it can be said that the personal risk in which they place themselves while on duty is not very standardized or predictable, as the criminals they confront vary from the petty thief to the fierce Death Eater.
