2 families targeted in separate armed home invasions in Philadelphia

Two families were targeted in separate armed home invasions in Philadelphia this weekend, authorities said, and the search is on for the suspects in both cases.

Philadelphia police said they're looking into if the cases could be linked, but they said "at this time, there’s no indication that they are."

The first home invasion was around 1:41 a.m. Saturday, right as a family arrived home, police said. Armed suspects pushed their way into the house, restrained the family and stole belongings, police said.

The suspects then abducted two family members at gunpoint and took them to another location about 4 miles away where the suspects "continued their criminal actions and inflicted physical harm," police said in a statement.

Responding officers tried to intervene at that second location, with one officer firing a gun, police said. No one was hurt and the armed suspects fled the scene, police said.

Police said the family suffered injuries, but the department did not elaborate.

Then, at around 12:14 a.m. on Sunday -- at a house about 4 miles away from the home targeted on Saturday morning -- a dad was sitting on his front porch when a man dressed in black and armed with a gun approached him, police said.

The gunman forced his way into the house and used zip ties to tie up the man, his wife and their daughter, police said.

The gunman stole $1,000 in cash, hit the dad on the head with the gun and then fled the scene, police said.

The victims were able to quickly free themselves and call police, authorities said.

The dad suffered head injuries and the daughter reported abrasions from the restraints, police said.

Both investigations are ongoing.
