A Bar Mitzvah To Remember

Heads will roll on this (as they'd better, but Stern has the best connections, so who knows?):

Mayor Bloomberg said today that the city has launched an investigation into who allowed a wealthy inmate to host a lavish bar mitzvah behind bars for his son at the downtown lockup known as the Tombs.

"Clearly, this is not something that should have taken place," Bloomberg said.

The Post reported in an exclusive story today that Tuvia Stern, a financial-scam artist who jumped bail and spent nearly 20 years on the lam, was allowed to hold the party.

City Correction Department officials permitted him to use his own caterer, who supplied kosher food, china, forks -- and knives -- for about 60 guests who partied and danced the hora for six hours in the jailhouse gym.

Stern's family and friends were allowed to keep their cellphones -- normally a huge security no-no. And Stern was given the OK to dress in clothing appropriate for the occasion.

The guest list at the jail included several prominent rabbis as well as Yaakov Shwekey, a popular Orthodox singer, and a band.

The city threw in its own present -- overtime pay for the correction officers staffing the soiree.

The Dec. 30 bash was so successful that jailbird Stern chose the same venue four months later for his daughter Breindy's engagement party for 10 family members, sources said.
