Police in Minnesota have arrested a man they say killed two people and injured two others when he went on a “shooting rampage” at and near a homeless camp. Around 4:40 a.m. Sept. 18, Minneapolis police responded to a double shooting at a homeless encampment, according to a news release.

Minneapolis police say the protocol also led to the arrest of a man suspected of three shootings near homeless encampments. Two men were killed and two others were injured. On Thursday, Minneapolis Mayor Jacob Frey said he would direct city staff to accelerate the closures of homeless encampments throughout the city.

The incidents occurred within a 16-hour period in Minneapolis’ Phillips neighborhood. No motive had been established as of late Wednesday.
