MILWAUKEE (CBS 58) -- The Milwaukee County Sheriff's Department arrested a woman after an argument led to her shooting bullets from her own open sunroof Saturday afternoon, June 13. 

MSCO deputies responded to Lake Park for a shots fired call around 6:25 p.m. 

Upon arrival, they learned that an argument had broken out at a family picnic, which led to a 36-year-old woman to stormed away.

She then put her child into her car, drove away and fired two shots through her open sunroof as she pulled away.

No injuries were reported and it is unclear if she was invited. 

Deputies later took her into custody. 

Criminal charges are pending and an investigation is ongoing.
