Missoula, MT -

Residents in a three-block area of northern Missoula were evacuated after a landlord found bomb-making chemicals in a tenant's apartment.

Four four-plexes and a mobile home park were evacuated Monday morning so police could clear a 100-yard area around the apartment.

Missoula police said the landlord entered the apartment Monday morning and found chemicals he believed could have been used to make methamphetamine. Responding officers instead found chemicals needed to make bombs.

At mid-day, experts were in the apartment trying to analyze the compounds and determine best to remove the chemicals.

Police said a 26-year-old man has been detained for questioning in Kalispell.
