Swiss security has more holes than its cheese.

A container holding $600 million worth of loose diamonds was left sitting with a gaping hole on the bottom at the same JFK warehouse where thieves swiped $1.2 million in cash last week, The Post has learned.

In both instances, the crates arrived on Swiss airlines flights from Zurich.

“Someone could have put their arm inside the cargo container and taken what was inside,” a source said.

A Port Authority cop spotted the damaged cargo container Thursday at around 1:35 p.m., an hour after the flight landed, sources said.

Although it was still sealed, the container “had a gap of several inches on the bottom and parcels were visible inside.”

The contents included up to $600 million worth of diamonds that were destined for jewelers in New York City and elsewhere, sources said.

“It was extremely easy for anyone to put in their arm there and take something out of there,” the source added.

Police supervisors and representatives for SwissPort, the cargo shipper, moved the container to a “secure unpacking location” where officials compared the inventory inside with a shipping manifest.
