Sinn Fein policing spokesman Gerry Kelly has sought legal advice after he was filmed apparently using bolt cutters to remove a clamp from his car.
The north Belfast MLA removed the device after finding his car had been immobilised while he was at a gym in Belfast city centre on Friday morning, the party said.
Sinn Fein confirmed Mr Kelly removed a clamp from the front wheel of his car after footage emerged on social media.
The footage appears to show him kneeling down to remove the device from the vehicle's right-hand wheel, before resting it against a nearby wall.
A pair of bolt cutters appear to be lying beside the wheel.
On Saturday evening, a Sinn Fein spokesman said: "Yesterday, Friday 2 February, Gerry Kelly MLA returned to his car after an early morning gym session to find that his car had been made immobile by a clamp just after 7.20am.
"He removed the clamp from the front wheel. He left the device nearby and drove off to pre-arranged meetings.
"His solicitor is dealing with the matter and he will be making no further comment at this time."
