HAMLET, N.C. -- A North Carolina city has canceled all of its July 4th events due to "heightened security concerns."

Downtown Hamlet posted on its Facebook page, saying the planned festivities have been canceled.

Hamlet Police told NBC Charlotte that the city had received numerous threats of violence tied to a homicide that took place last week. On June 28, 20-year-old Tierrell Martin was shot and killed at a convenience store in Hamlet, according to a report from the Richmond County Daily Journal.

The Hamlet Police Department arrested three people suspected of gang activity Tuesday night. They say the suspects were found nearby where the Fourth of July events were supposed to take place.

The town posted on Facebook thanking everyone for their cooperation and explaining that the decision was in the best interest of the people.
