Some students at Allen High School say they saw a lot of new faces walking the halls Thursday.
The people weren't new students, they were extra security guards a day after a 15-year-old student was shot in the leg a block away.
Students tells us they noticed at least seven new security officers.
They also say even more security showed up as it got closer to dismissal time.
It was easy to spot people keeping an eye on the more than 3,000 students who attend William Allen High School.
"As the day went forward, more security guards were in the school and more cops were around," said Lawrence Bethea, a student at Allen.
"There was a lot of security. It was, like, really scary," added Mirca Proano, another student at Allen.
The Allentown School District and the Allentown Police Department added the personnel after a 15-year-old girl who attends Allen was shot in the leg at 16th and Turner streets Wednesday afternoon.
"We don't want to see anything happen again," said Roger Maclean, chief of the Allentown Police Department. "We want to quell this. We want to get the investigation through. We want to be able to arrest the people that were involved in this."
Investigators have been working on the case since the shots rang out Wednesday afternoon.
"There is definitely some friction among groups or among people that we are looking at," said Maclean.
Students say they did feel a little safer in the school Thursday.
Some say this many people watching over them won't last.
"It's something they'll do until it calms down," added Bethea.
Chief Maclean tells us the shooting was not random and people shouldn't worry.
He believes the shooting was between two groups that had a disagreement and that the victim may have been caught in the crossfire.
