Dallas Police now say at least nine people have been attacked and robbed in the Oak Lawn neighborhood in the past two months.
In each case, officers said the victim was a man and alone in a public place during the nighttime hours when he was attacked.
Two of the assaults were so severe, one man ended up in the hospital with a skull fracture after he was hit in the head with a baseball bat and another man landed in the hospital after the suspects stabbed him.
The latest news from around North Texas.
"It's obvious these people are going in a particular neighborhood and targeting particular people in that neighborhood," said Rafael McDonnell with the Resource Center for the LGBT community.
On Monday, police released some details about the attackers.
Police said five of the offenses were reportedly committed by a group of two to four Hispanic males who knocked their victims to the ground and punched and kicked them while stealing their property.
They believe a white Ford van was used during at least one of the robberies.
Two other attacks were reportedly committed by a single black male who pointed a gun at his victims and stole their property.
He is described as being 28 to 30 years old, approximately five-feet, 10-inches tall and 150 pounds.
In one offense he was wearing a yellow shirt and blue jeans, and in the second he was wearing a gray shirt and black pants.
There is no suspect vehicle information for this individual.
Two offenses were reportedly committed by one to three black males who also knocked their victims to the ground and punched and kicked them while stealing their property.
One suspect is described as being 18 to 20 years old, approximately five-feet, eight-inches tall and 150 pounds. While the other two suspects are both described as approximately five-feet, 10-inches tall and 185 pounds.
There is no suspect vehicle information for those men.
McDonnell said some businesses in the area are installing additional security cameras and residents are being encouraged not to walk alone at night.
