PINELLAS PARK, Fla. — A Pinellas Park police officer is recovering after being shot in the arm Tuesday night after an exchange with a suspect at a gas station.

Another officer narrowly missed being run over as the suspect drove off from the scene.

The incident happened at 9:40 p.m. at a Circle K gas station during a call for service at 4900 Ulmerton Road.

The officer, Jacob Derr, is in stable condition at an area hospital and the suspect is in custody.

A second scene was located where police rammed the shooter who they say fled. That happened in the 900 block of 22nd Avenue South, after a short pursuit on I-275 with the help of the sheriff's office helicopter.

Police say this started at the Circle K as a 911 call from a woman locked inside a bathroom. She said her boyfriend had roughed her up.  

When Derr arrived, investigators say the boyfriend, 24-year-old Calvin Brockington, got out of his car and opened fire.

Authorities said Sinclair shot Derr in the arm then car jacked someone pumping gas.

As he sped out, he almost ran over a second responding officer.

The Pinellas County Sheriff's Office says the responding officers knew who they were coming for.

"He had information regarding the domestic again that (Brockington) was anti-law enforcement, he was somebody that possibly had a warrant out for his arrest, and that's what he knew going in to this," said Pinellas County Sheriff Bob Gualtieri.

Brockington faces at least two counts of attempted murder of a police officer, as well as other felonies.

Officer Derr was the only person injured and is expected to make a full recovery.
