TULSA, Oklahoma - A man accused of impersonating a Tulsa Police officer has been taken into custody after leading authorities on a high-speed chase through Oklahoma City Wednesday afternoon.

In a phone call to police, Barry Lloyd Baker Jr., 33, said he was suicidal. When officers showed up to do a welfare check at the 3000 block of West Reno in Oklahoma City, Baker started a chase in a newer-model white Ford King Ranch pickup truck, believed to be equipped with a police-style radio.

Police said Baker tried to run over a Oklahoma Highway Patrol trooper who was putting out tire deflators. The pursuit continued near Northwest 44th Street and Western Avenue, where Baker continued to drive with flattened tires.

He was finally captured at Interstate-44 and Western Avenue.

At least 27 police cars responded to the pursuit.

Baker was identified as a wanted man after he missed a Tuesday court appearance for charges of impersonating a police officer.

Tulsa Police were actively looking for Baker, who uses the alias "homicide detective Matt Baker."

Baker has a Facebook page where he publicly chronicles his lifetime struggle with obesity and his quest to lose more weight and join law enforcement. The "about" information says:

"I weighed in at a heart stopping 571 pounds. I was OVER a QUARTER OF A TON. September 22nd, 2010 I had the full gastric bypass and now, over 250 pounds lighter I am on my way to be a full time Police Officer and have a better, longer life..."

Baker is accused of impersonating police on two occasions on or about January 9, 2012 and on or about May 21 2012.

In the earlier incident, an affidavit alleges Baker sold a set of Freedom Arms Commemorative .22-caliber Magnum revolvers for $350. He deposited the victim's personal check but never delivered the firearms, the document says.

The victim in the case told authorities each time he asked Baker about the guns, Baker had an excuse as to why he couldn't deliver them, according to the affidavit. The victim said Baker has activated an audible police-style siren and he gave "a reason of being ‘on a call' as an excuse for not delivering the guns" while speaking with the victim on the phone, the affidavit says.

Baker reportedly showed the victim a badge and a white Ford Crown Victoria, which he claimed was an undercover police car, in an attempt to gain the victim's confidence, the affidavit says.

According to court documents, a representative for the Oklahoma Council on Law Enforcement Education and Training is set to testify in the police impersonation case that Baker's CLEET certification to become a reserve officer is incomplete.

Baker also has open cases in Wagoner County for felony assault and battery with a deadly weapon and misdemeanor misuse of horns/warning devices and altering a license-plate decal.

Baker appeared in court June 4 on felony bogus check charges. Court documents allege he wrote a $2,000 check on a closed Fraternal Order of Police Credit Union account to purchase a 46-inch television, a Blu-Ray player, 3D glasses and extended warranties at Mathis Brothers Furniture.
