What's another black eye to the CPD.... A former Chicago police officer is accused of getting into an argument with a motorist in a funeral procession

A female former Chicago police officer is accused of getting into an argument with a motorist in a funeral procession, then lying during a trial and to her superiors that the motorist had hit her with a bottle.

Sylshina London, 36, has been charged with perjury. She joined the department in 2002 and resigned earlier this year as the 2010 incident was being investigated.

During the investigation by Independent Police Review Authority, authorities said they obtained police camera footage of the incident "which proved London’s claims against the woman to be false."

The incident occurred on March 19, 2010 near 79th Street and Vincennes Avenue as London was driving her car to work, officials said. London was late and began cutting in and out of a funeral procession, prosecutors said.

Debra Green, whose sister had died, noticed London and yelled at the officer, pointing to the funeral sticker on her windshield, prosecutors said.

When Green reached 100th Street and Vincennes, her car was stopped by police and she and other family members were "prevented from continuing on in the funeral procession to attend her sister’s burial, based upon Officer London calling in a false complaint," the state's attorney's office said.

Green was charged with battery based on London’s accusation.

During Green's trial on Sept. 21, 2010 London testified that Green threw a bottle at her while the two cars were stopped at 79th and Vincennes.

London said her driver's side window was open and the bottle flew in and hit her in the face. Prosecutors said they did not know about the police video at the time, and Green was found guilty based on London's testimony.

The video was discovered by IPRA, which was conducting its own investigation, and showed London’s driver-side window up, prosecutors said. The authority said it notified prosecutors after learning of London's testimony and Green’s conviction.

Green’s battery conviction has been dismissed.

London's bail was set at $30,000 today.

The head of the Independent Police Review Authority commended the state's attorney's office for following through on questions originally raised by the IPRA.

“The officer’s actions are a disservice to the many men and women of the Chicago Police Department who are honest and work hard to do a good job,” said Ilana Rosenzweig, chief administrator for the IPRA.
