In the span of three hours Friday morning, Lafayette police were called to investigate a home invasion, two attempted robberies and two armed robberies.

“It was definitely a higher volume of incidents than we’ve seen in the past,” said Lafayette police spokesman Cpl. Paul Mouton.

No arrests had been made as of Friday evening. Investigators are not certain if any of the incidents are related, but one of the robberies is believed to be connected to another robbery early Thursday morning, Mouton said.

The first incident on Friday was a 2 a.m. home invasion in the 300 block of Roosevelt Street in which a man forced his way into the back door of a home and then fled after a brief tussle with the resident.

The resident received minor injuries.

Then at about 3:30 a.m., a man wearing a dark, hooded sweatshirt and a bandana over his face demanded money from a clerk at the Studio 6 motel at 1441 SE Evangeline Thruway but ran away after the clerk refused.

Half an hour later, at 4 a.m., a man armed with a handgun walked into the Cracker Barrel convenience store at 724 Eraste Landry Road and demanded money.

The clerk didn’t hand over any money, police said, and the would-be robber ran off toward Macon Street.

At 4:35 a.m., police responded to the Travelodge hotel at 1101 W. Pinhook Road, where two armed men entered the business, stole an undisclosed amount of money and ran off, police said.

Ten minutes later, three robbers armed with handguns stole an undisclosed amount of cash from the McDonald’s restaurant at 1430 NE Evangeline Thruway and then sped away in a silver, four-door car.

Mouton said the three robbers in that case are believed to be responsible for the armed robbery of the Cracker Barrel store at 5714 Johnston St. at 2:20 a.m. Thursday.

In both cases, the robbers wore hooded sweatshirts and covered their faces, Mouton said.

“In the others, we are not too sure they are related,” Mouton said, adding that the description of the robbers and the way they carried themselves don’t seem to match.

He said investigators are actively working all the cases and reviewing security video from the businesses that were robbed and videos from nearby businesses.

“Our detectives are looking at everything, from video to canvassing the area,” Mouton said.

Police asked anyone with information on the incidents to call Crime Stoppers at (337) 232-TIPS.
