The lawyer for a Queens man facing robbery and assault charges after a shooting in the Roosevelt Field mall days before Christmas said Tuesday that a grand jury has indicted his client.

Oliver Lee, 21, of Little Neck, chose not to testify before that Nassau grand jury, the defendant’s attorney, Anthony Colleluori, also told Newsday.

The Mineola attorney said he won’t know what charges are in the indictment until it is unsealed, and the defense hasn’t received an arraignment date yet.

Authorities have alleged that on Dec. 22, Lee snatched a Rolex worth more than $18,000 inside a Tourneau store in the Garden City shopping center, showed a handgun and tried to flee.

But authorities also have said the store’s security guard, a retired NYPD detective sergeant, stopped the gunman and got into a violent struggle during which a round was fired from Lee’s gun, striking a 67-year-old mall worker in the shoulder.

Police said two unarmed mall security guards helped restrain Lee and an off-duty NYPD inspector also helped handcuff the man.

Colleluori said the indictment was expected, and the defense wants to talk to more witnesses who saw what happened in the store.

The incident sent Christmas shoppers scrambling for safety.

“We’ve had a couple witnesses come forward who have told a little bit of a different story about what happened,” the attorney said Tuesday.

The district attorney’s office declined to comment Tuesday.
