OAKLAND COUNTY, MI - A couple in their 60s were bound with zip ties by four male suspects who threatened to set them on fire during a home invasion in Independence Township.

Deputies with the Oakland County Sheriff's Office responded around 1 a.m. Friday, Dec. 1 to the 7000 block of Chipmunk Hollow off Dixie Highway (M-24) for a report of a home invasion.

A 63-year-old Holly Township resident told police he was watching television with his girlfriend, a 64-year-old Independence Township woman, in the basement of the home when four suspects wearing ski masks ran down the basement stairs.

Brandishing firearms, the suspects zip-tied the couple's wrists and ankles while demanding money. The suspects also poured gasoline on the victims and threatened to set them on fire if they did not give them money.

Approximately $7,200 in cash was taken by the suspects from a closet at the home before fleeing the scene.

The male victim previously owned a marijuana dispensary and believed the home invasion was related to the business, police said.

He was repeatedly kicked in the rib cage during the home invasion and taken to a local hospital for treatment of non-life threatening injuries.

An Oakland County Sheriff's Office K-9 unit responded and established a track that was later terminated when it was determined by law enforcement officials the suspects had left the area, possibly in a white van.

The incident has been turned over to detectives with the Oakland County Sheriff's Office for additional investigation.
