LYNN-Multiple shots fired outside of Lynn Classical High School resulted in police locking down the school for over an hour around 2:30 p.m. Friday.Approximately 500- 600 kids, roughly half of the student body, were trapped inside the building during the incident. No injuries were reported.Steven My, 18, of 19 Chase St., #1, Lynn, was arrested and charged with disorderly conduct and trespassing shortly after the incident occurred.According to police and witnesses, several Asian males all dressed in red clothing with a pistol, a shotgun and a rifle, were seen in a 2005 red Nissan Pathfinder at the time shots were fired.The SUV reportedly fled in the area of Walnut Street, and several shell casings were later found on Holyoke Street near the school.Anxious parents paced back and forth on the front lawn of the school, sending text messages their children inside the building.Karen Ashwell, mother of Megan Ashwell, a senior at Classical, said her daughter called her on her cellular phone to let her know what was going on.?I have a red SUV and I was almost pulled over by the police because they were looking for the same vehicle,” she said in a panic. “I just thought, oh my God almighty, what is going on?”Carlos Perez said while he was picking up his two daughters from Breed Middle School, he witnessed the incident unfold before his eyes.?I got the license plate number of the vehicle and gave it to the police,” he said. “I followed the car and saw Cambodians in it?I saw one with a rifle in his hand, he (the driver) cruised through a red light. I was definitely scared as a parent to see that.”After about an hour, students began to slowly trickle out of the building, hugging their parents and friends, and shedding tears of joy that everyone was safe.Socrates Trinidad, a junior and a member of the baseball team, said he spent about an hour in silence with six of his fellow teammates in a classroom, huddled together for safety.?We heard a lot of banging on the lockers and doors, we didn?t know what was going on, if it was the police or a gunman,” he said. “Some of the kids were hiding under tables or sitting in the corner, and we were all pretty nervous and scared.”Several students said they believed the shooting was a result of a fight that previously happened at the school, while others said it was the work of gang members.?I was scared for my life,” Daphnee Ozual, a junior at Classical said. “Most of the kids were calm, but I was scared. Everyone is hearing different stuff right now about what happened.”Superintendent Nicholas Kostan said people were seen with a gun in the area when a shot was allegedly fired across the street from the school.?The good news is, as far as we know, there are no injuries,” he said. “It was just a tough way to end the week. We very seldom have problems here at Classical.”Kostan said he was unsure if the gunman was a Classical High student, but did mention that he saw an Asian male in handcuffs with police.?The Lynn police did a tremendous job, and the teachers and the students were fantastic in the way they reacted to this and the way they cooperated with police. They all did the right thing, followed procedure and they knew exactly what to do.”Anyone with information about the shooting is asked to contact Lynn police at 781-595-2000.The investigation remains ongoing.
