POCATELLO, Idaho (AP) — Police in Idaho have fatally shot a 23-year-old man wielding a knife outside of a south Pocatello residence after he fled from officers, authorities said.

Pocatello Police officers responded to a disturbance call Tuesday involving a knife-wielding man and a woman, the Idaho State Journal reported.

The relationship between the man and woman and what prompted the disturbance is unclear.

The disturbance was reported by a family member, police told the Journal during a Wednesday press conference.

The man fled from the scene in a vehicle and police confronted and shot him less than two blocks away, authorities said. Police attempted to perform live-saving efforts on the man.

No other injuries were reported.

Multiple agencies responded to the scene including the Pocatello Fire Department, Chubbuck Police Department, Bannock County sheriff’s office and Idaho State troopers.

An investigation is underway.
