Even though a grand jury met this week but took no action against one of two Baton Rouge men who were arrested in a terrifying Jan. 31 home invasion and armed robbery in an upscale neighborhood south of LSU, the parish’s top prosecutor said Friday the probe is active and ongoing.

“The case is still open. The police continue to investigate and follow leads,” East Baton Rouge Parish District Attorney Hillar Moore III said.

A woman and her four children were held at gunpoint during the early morning incident in the Riverbend Subdivision that led to the arrests of Lawrence Isaac, 20, and Michael Anthony Lewis, 28, on armed robbery charges.

An East Baton Rouge Parish grand jury Wednesday considered an armed robbery charge against Isaac but neither indicted nor cleared him. Isaac has been released from jail.

Moore acknowledged that the crime was egregious and said the Baton Rouge Police Department and his office have paid much attention to it.

The district attorney said he could not elaborate further on details or issues in the case.

The homeowner, Rania Ahmed, told The Advocate previously that she was awakened by two men who covered her mouth and pointed a loaded pistol at her. The men dragged the rest of the family out of their beds, beat several children and tried to tie the family up with duct tape, she said.

Ahmed could not be reached for comment Friday.

Her 18-year-old daughter’s jaw was broken during the home invasion, and her 15-year-old son’s arm was cut with a pocket knife.

Ahmed, the owner of Akasha Market in Tigerland, has said the men threatened the family and demanded they “show us the money” — mistakenly believing there was a large amount of cash in the home.

One of the children managed to call 911 during the invasion.

An affidavit of probable cause says Isaac, 246 Old Rafe Meyer Road, fled the scene and led officers on a foot chase before being taken into custody several blocks away. The thieves, according to a police report, stole a PlayStation 4, two smartphones and a bag containing two wallets and a gold ring.

Moore encouraged anyone with information about the home invasion to contact the Police Department, his office or Crimestoppers.

Ahmed told police she believes Lewis, 4445 Alvin Dark Ave., is the same gunman who robbed her Bob Pettit Boulevard store of about $5,000 on Jan. 4. The shop also was robbed Jan. 20 by a different man.

Police have not identified Lewis as a suspect in the first robbery, but detectives are investigating any possible connection between that incident and the home invasion.

Lewis is charged with a drug offense, prosecutors said.
