Tamper, tamper: brawl att’y

A Port Authority cop who “saw stars” after getting KO’d trying to make peace during a Brooklyn bar brawl may be on the hook for tampering with a witness.

Officer Ryan McCarthy suffered a broken jaw when he got hit outside the Kettle Black in an April 2010 fight.

But Arthur Aidala, an attorney for one of the five men charged with assault, said he’ll go after McCarthy today for testimony that’s “night and day” from what he told a grand jury, and for allegedly trying to coerce a witness into testifying.

Earlier, McCarthy said he contacted pal Antonella Manieri when he learned that she might not testify.

“I text-mailed Antonella and I told her that I was disappointed,” McCarthy said.
