WAKEFIELD (CBS) – A State Police helicopter made a precautionary landing on a baseball field in Wakefield Thursday morning after two warning lights came on.

The chopper landed safely on the field behind a Shaw’s Supermarket near Water Street off Route 129 around 10:30 a.m.

Two troopers, a pilot, and a tactical flight officer were on the helicopter at the time of the landing.

No one was hurt.

The copter returned to the State Police air base in Lawrence around 2 p.m.

“A mechanical check determined that a small amount of moisture behind the control panel caused two indicator lights in the cockpit to illuminate. There was NO mechanical problem with the aircraft,” State Police said in a statement.
