Riverhead Town police said an officer responded to the runway at the Enterprise Park at Calverton Sunday afternoon in response to a call saying numerous vehicles were lined up on the property in preparation for a race.
When an officer arrived at the scene, a number of motorcycles reportedly headed south through an unsecured gate and onto Grumman Boulevard, where they escaped. Police said extra patrols were conducted at EPCAL as a result of the incident.
Officials said motorists and motorcyclists have been racing illegally at EPCAL for years. In November police cracked down on members of an auto racing club that used the EPCAL as a racetrack.
