A group of armed robbers who make their victims take off their clothes hit again over the weekend, the latest in a string of robberies all with a similar modus operandi.

In the latest robbery, which targeted a Broward County, Florida, Subway restaurant Monday night, the robbers’ victim was a woman who is eight months pregnant. The robbery was the fifth such crime that had similar circumstances in the last two months. All of the robberies have been caught on camera.

“It seems to be that is their strategy, to take their clothes off,” said Keyla Concepcion of the Broward Sheriff’s Office.

On November 9th at the Rite Way Food Market in Pompano Beach, a customer and clerk were ordered to the back of the store, at gunpoint, where they were both forced to take off their pants. On October 31, a victim at a Pompano Beach convenience store was hit with a gun and shot in the leg.

October 28th, a Tamarac Subway was hit around 10:30 p.m. where employees were robbed at gunpoint before being dragged to the back of the store and ordered to strip. On October 7th, an employee of a GameStop in Plantation was ordered to drive the robbers around before dropping them off in Lauderhill.

Investigators haven’t said if all of the crimes are related, but said all of them are similar in their actions during the robberies.
