FLINT (WJRT) UPDATE: Police arrested the fourth suspect around 6 p.m. Investigators say there are no more suspects outstanding from the incident.
(4/17/2019) - The Flint Development Center was placed on lockdown after someone fired a gunshot outside and someone involved in the confrontation got inside.
Police from across Genesee County swarmed the school in the 4100 block of Martin Luther King Avenue around 10 a.m. after receiving reports of a confrontation outside the building and a single gunshot.
Police say staff and students from the school were involved in the confrontation, but none were injured.
As the people involved in the confrontation scattered, one of them made it inside the school, according to Flint Police Department Det. Sgt. Tyrone Booth.
The school immediately went into lockdown. Booth said all staff and students in the building are safe, but they remained in a lockdown until 12:20 p.m. while police worked to clear the school.
However, students and parents thought the worst as the incident unfolded and police swarmed the building. One mother said her daughter called from inside the school while she was busy calling family members to pray.
"I'm just glad i wasn't one of the mothers -- or the parents period -- that something happened and I come up here and they are saying, 'I'm sorry' and I have to identify her," the mother said. "That did not happen and I thank God."
The school closed for the day after the lockdown was lifted. Police remained on the scene while students were sent home for the day.
Authorities arrested three people at the scene and investigators were looking for a fourth suspect Wednesday afternoon. Police don't believe the school was a target of the shooting.
Police were still investigating what led up to the confrontation Wednesday.
