It took TSA agents 10 minutes yesterday to call cops after a Manhattan woman walked past JFK Airport scanners with a dagger in her bag.

She was arrested but not before the security bungle shut down JetBlue’s screening area in Terminal 5 for nearly two hours.

Port Authority police are supposed to be called immediately in the event of a security breech. Yet this slip-up was just the latest in a string of embarrassing security mishaps — three in February — by the federal Transportation Security Administration.

PA Officer Dante Castro-Recio arrested Gabrielle Olsen, 26, of Washington Heights, at 6:30 a.m. — 10 minutes after cops were notified — on a weapons-possession charge.

TSA agents had initially flagged her for having a bottle of liquid in her bag. The screeners confiscated the bottle but missed the antique knife, police sources said.

It wasn’t until after she had departed the security-check area at 6:09 a.m. that the knife was identified on a screening-machine X-ray.

Olsen told police that her father, an antiques dealer, had given it to her for protection, police sources said.

The screening area reopened at 8:28 a.m.

Eight days ago, a suspicious passenger slipped past three TSA officials at JFK, shutting down a British Airways terminal for more than two hours as cops searched for bombs.

Earlier last month, a TSA agent mistakenly let a civilian get past a checkpoint. The man was merely trying to greet his wife.
