(Radio Iowa) – A traffic stop for an equipment violation took a tense turn last (Tuesday) night in Des Moines. Des Moines police say the unidentified 41-year-old sped away from the traffic stop and led officers on a chase that ended outside a house. The man ran inside and police say he barricaded himself in the basement and armed himself with what’s described as a makeshift spear. Other residents of the house moved outside to safety as the suspect — according to police — made homicidal statements, including threats to stab officers.

After seven hours of negotiation proved unsuccessful, a tactical unit deployed tear gas into the house and took the suspect into custody. A fire broke out inside the house as the event ended, the cause of which is under investigation.
