Police say three adults have been killed at an in-home day care in a Minneapolis suburb.

Brooklyn Park police haven't released many details about the killings around 6:30 a.m. Monday.

Inspector Todd Milburn wouldn't say whether any children were present at the time, but he says no one else was hurt.

Milburn says a suspect fled on a bicycle.

Officials at the nearby Hennepin Technical College say they locked down the school after police told them there had been a shooting in the area.

Hakeem Hughes, an 18-year-old student who lives close to the day care, says police told him to stay inside because a gunman was on the loose.

No arrests have been made.

State records show the home was licensed to care for up to 12 children.
