At least two Arkansas police officers — including Hackett Chief of Police Darrell Spells — were shot in Sebastian County on Wednesday and authorities were descending on the mobile home where the suspected shooter was believed to be barricaded inside.

A deputy who was shot was in critical condition and Spells was still hospitalized at Sparks Hospital in Fort Smith, NEWS5 reported.

Police negotiators entered the mobile home around 11 a.m.

The accused shooter was identified as Billy Jones, an official from the Sebastian County Sheriff’s Department told 40/29 News. Jones was described as having animosity towards law enforcement officers. Spells and the deputy were at Jones’ house to serve a warrant around 7:20 a.m.

A huge contingent of heavily armed police surrounded Jones’ home after the shooting.

“We believe him to be holed up currently,” SCSD spokesman Philip Pevehouse told The Arkansas Democrat-Gazette.

Three local departments and the state police were responding to the incident. One officer drove at least 50 miles to get to the scene, NEWS5 reported. Two police helicopters had been deployed and The Arkansas Democrat-Gazette said a SWAT team was on site.

Police said the suspected shooter was carrying a semi-automatic weapon, NEWS5 reported.

A person who answered the phone at the Sebastian County Sheriff’s Office declined to provide further information on the incident and told that the department was “under emergency.”

Spells, identified as a victim by NEWS5, took over as police chief in December 2013 in Hackett, a town of just over 800 people about 170 miles west of Little Rock. The other officer who was shot was a deputy, but no name was given.
