A 32-year-old Cheyenne man accused of assaulting several people, including a police sergeant, has waived his right to a preliminary hearing.

Matthew Dausman was arrested on Jan. 29 after allegedly breaking into his father's home and threatening to stab him with a knife.

When a police sergeant contacted Dausman, he reportedly charged the sergeant, causing him to lose his balance and fall. Dausman then fought with the sergeant, unsuccessfully trying to disarm him.

The sergeant, who received cuts and bruises, was able to detain Dausman until additional officers arrived.

Dausman is charged with aggravated assault and battery-threatens with a weapon, two counts of interference with a peace officer-injury and attempted interference with a peace officer-disarms. If convicted, he could face up to 35 years in prison.

Dausman remains jailed on a $20,000 cash bond. His arraignment date has yet to be scheduled.
