One of the two suspects in the shooting rampage in Kansas City, US state of Kansas, in which four people were dead and another five wounded, was detained, according to police said on Monday.

The suspect, identified as 23-year-old Javier Alatorre, was captured and taken to custody late Sunday, hours after police responded to a shooting spree at Tequila KC bar in downtown Kansas City, and searched for what they believed to be two suspects, the Xinhua news agency reported.

Kansas Police Department (KCKPD) said in a statement that the second suspect, 29-year-old Hugo Villanueva-Morales, “was still at large and should be considered armed and dangerous.”

Authorities searched for Hugo Villanueva-Morales and warned that he should be considered armed and dangerous.

“If you see him or know of his whereabouts, do not approach,” Kansas City, Kansas, police further said in a statement.

Both men face charges including four counts of first-degree murder, and bond for each was set at $1 million.

On Sunday, Thomas Tomasic, KCKPD spokesman said that the police were still trying to piece together what happened at the bar through the help of surveillance video and witness accounts.

Investigators believed the shooting was an isolated incident that did not seem to be “racially motivated.”, Tomasic added.
