Police on Tuesday arrested four people who had barricaded themselves inside a Kansas City residence and refused to surrender.
The incident began about 8 a.m. when officers were sent to the area of 26th Street and Madison Avenue in response to an armed robbery. A construction worker said two males held him up at gunpoint. The robbers fled into a residence in the 900 block of West 27th Street.
Police called in negotiators and initiated an Operation 100, which is the police term for handling a hostage or standoff situation.
The two men, both in their late teens, and two females surrendered about 9:30 a.m. No injuries were reported.

Detectives obtained a warrant to search the home. Police did not release details Tuesday about what they found in the search.
