Concord Police are seeking information and witnesses after a proposed Facebook Marketplace exchange in the city ended with the seller pointing a gun at the buyer. 

The two parties had agreed to meet on Monday in the parking lot outside the Fort Eddy Road Petco for an Apple iPhone purchase, according to Concord Police. The buyer told police that the seller pointed a gun at him and threatened to shoot, and police were called at 12:25 p.m.

The suspect was driving  “a white-colored vehicle, similar in shape and size to an Infinti Q50 with tinted windows and an unknown Massachusetts license plate,” police said in a press release. They are requesting that any witnesses or others with information step forward to assist their investigation by contacting the department.
