A San Francisco Municipal Transportation Agency bus driver was charged Monday with allegedly lying about being injured in a 2012 robbery – an attack that authorities said never happened.

The report in SFGate says that Velma Louise Jones, 61, of Vallejo told San Francisco police she was robbed while working a shift on June 1, 2012, prosecutors said. She filed a workers’ compensation claim, saying she suffered head injuries.

But prosecutors said surveillance video from her bus contradicted her story. While three books of transfer tickets were stolen that day, Jones was allegedly taking a break away from the bus during the theft. The San Francisco district attorney’s office said it began investigating the case after being contacted in August by the insurance company dealing with the workers’ compensation claim.

Jones was charged with four felonies: workers’ compensation fraud, filing a fraudulent insurance claim, submitting documents in support of a fraudulent insurance claim and making false statements in connection with an insurance claim. District Attorney George Gascón described Jones as a city employee who “attempted to take a paid vacation from work at the expense of San Francisco taxpayers.”

Daniel Siegel, her attorney, said the case was a misunderstanding. Though Jones was not on the bus at the time of the attack, he said, she was outside it and the man who stole her transfers had shoved her out of the way, knocking her head against the bus. She withdrew her claim, Siegel said, when she “decided it wasn’t that big of a deal.”

Jones, released on $50,000 bail, appeared in court Monday. If convicted, she faces a maximum of eight years in state prison or county jail. She is on paid leave, according to the Municipal Transportation Agency.
