FRIDLEY, Minn. (AP) -

Anoka County authorities have charged four people in connection to a Minneapolis-area stabbing that left two 21-year-old men in critical condition.

Prosecutors charged two men and two women Tuesday in connection to the Saturday stabbing of Yani Singh of Columbia Heights and Anthony McCollum of Hilltop.

Authorities say the 22-year-old women asked the 21-year-old victims for a ride after leaving a Fridley bar. They say a 25-year-old man and a 20-year-old man stabbed the victims when they dropped the women off in a parking lot.

The county attorney's office says both men required emergency surgery and remain in critical condition.

The arrested men face charges including attempted murder and attempted aggravated robbery. The women face charges including aiding and abetting first-degree assault.

Their bonds range from $250,000 to $1 million.
