A Brentwood man is facing disturbing charges of aggravated cruelty to animals and harassment.

According to Suffolk police, the 23-year-old, who was not named, found a Chihuahua on May 9 that escaped from a home in Central Islip.

After keeping the dog for nearly a month, the man contacted a family member via FaceTime on June 1 and strangled the dog while threatening the family member during the call.

Detectives and officers from the Third Precinct recovered the dog’s remains at a waste transfer facility in Holbrook on June 4.

The Brentwood man was transported to Stony Brook University Hospital for an evaluation.

Police say the SPCA assisted in the investigation.
