MADISON, Wis. (WMTV) -- A 15-year-old suspect was arrested Thursday morning in connection with a shooting on a Madison Metro city bus, police said.
Authorities were called to Pflaum and Monona Drive near La Follette High School shortly before 4 p.m. Wednesday following a report of shots fired on a city Metro bus.
Dane County dispatch said La Follette High school, Monona Grove High School, and Sennett Middle School were on lockdown during the incident.
A 17-year-old boy was shot in the leg by a 15-year-old that he knew, police said. The 15-year-old then ran away from the scene.
A second student also sustained minor injuries. The 16-year-old student was grazed by a bullet, but did not need to receive medical treatment.
The 17-year-old's injuries are non life-threatening. Madison Police said they believe that the shooting was unintentional, and are looking into how the student got the gun, as well as whether the student had it in his possession during the school day.
After the shooting that took place in Middleton earlier Wednesday morning, police said that the day had tested resources.
"We have had several people that were at the initial incident in Middleton respond out here as well," said Capt. Tom Snyder with the Madison East Police District. "So certainly that's difficult, and it's been a long day for people, it's been a stressful day. And for those folks who remain in Middleton, they're probably going to be there through the night. So taxing on resources, no doubt about it."
Madison Metropolitan School District's safety and security coordinator Joe Balles said that there is no reason for parents to be concerned. The school district is conducting their own investigation and will have an incident debriefing in the coming weeks to discuss updates in the investigation.
"When you have teenagers handling firearms that have not had a responsible adult train them in any way how to handle a firearm, accidents like yesterday happen. And that's really the tragedy of yesterday, young people handling a weapon, bad things can happen," Balles said.
In terms of preventative measures to ensure a weapon is not brought on school grounds Balles said, "If we get information that a student may be bringing a weapon to school, we will definitely work with our E-R-O-S in our school to intercept that student before step one foot into our building and make sure they are properly searched."
