CHULA VISTA, Calif. — A 75-year-old man and his dog were physically assaulted last week at a park in Chula Vista, according to authorities.

Around 7:35 p.m., the man was playing with his dog near the basketball courts at Heritage Park when a basketball player left the court to punch the 75-year-old twice and kick the victim’s dog, Chula Vista Police Department tweeted. A female also was nearby sitting on the ground by the court when the incident occurred.

Police described the attacker as a man in his 20s, around 5’8”-5’10,” 150-170 pounds, with a thin build and light brown skin tone. He had black, wavy, shoulder-length hair and was wearing a white shirt or tank top and unknown color shorts with white, black and red shoes. CVPD believe the man drove away from the scene with a female companion in a dark-colored sedan (possibly a BMW or Volkswagen Jetta).

Authorities did not explain the attacker’s motive or the conditions of the victims.
