Suffolk County Police were dispatched for a mad cow running amok in the streets and in backyards.

The police car that was damaged when the mad cow charged at it.

A rogue cow had to be tranquilized Friday when it broke loose from its farm, went for a wander, and rammed a police car on Long Island.

The runaway bovine was strolling around Medford when cops were called to corral it around 11 a.m., according to Suffolk County Police.

When a squad car arrived at the scene, the mad cow darted straight toward it — striking the vehicle before trotting away.

The officer inside was not seriously injured.

Police cornered the animal in the backyard of an abandoned house nearby. The cow was then subdued with a tranquilizer.

After the temper tantrum, the animal was returned to its owner in Medford, who reported it missing Thursday night.

It was in good health and not expected to make any escape attempts anytime soon.
