The incident took place between 6:00 a.m. and 6:30 a.m. Sunday in a ground floor unit of the Arborwood Condominiums on Gibbsboro Road.
Authorities say a woman in her 40s and her 17-year-old daughter were inside the home at the time of the incident.
Police say a man entered the apartment through a window and then ordered the two women from their bedrooms into the living room area.
The suspect then grabbed an object from the kitchen and used it to sexually assault both women.
The suspect then fled the residence.
Both women had to be transported to a local hospital for treatment of injuries sustained during the assault.
Action News spoke with the teen's stepfather Sunday evening.
"A father is supposed to be there for their daughter under any circumstances and for that one brief moment, that's what I'm trying to understand, how is a father supposed to feel?" he said.
The suspect was described as a black male, approximately 5' 10" tall, wearing a black hoodie and black gloves.
The same suspect is also believed to have committed an earlier break in Sunday morning of another ground floor unit in an adjacent building. During that incident, a male entered through a window but was frightened off by the resident's dog.
The Lindenwold Police Department is requesting all residents to be extra vigilant in keeping their doors and windows locked. They should report any suspicious activity to the police as soon as possible.
The Arborwood complex consists of approximately 38 two-story buildings with 10 to 20 residential units per building. In recent years, police say, the area has seen an increase in drug activity and related crimes; however, these two incidents do not appear to be drug related.
"We're cautious in this neighborhood anyway because of how bad it is, but this really makes it bad when you start hurting our kids," neighbor Stacie Isler said.
If anyone should have any information regarding these incidents, or information as to the identity of the suspect, you are asked to contact Detective Jim Barney of the Lindenwold Police Department at (856) 784-4800 ext 409 or at firstname.lastname@example.org.
