Universal City police arrested a man they say set a woman's car on fire after she refused to follow through with a deal to exchange sex for money.

Richard James Benavides, 39, was set to be booked in Bexar County Jail on one count of arson and one count of obtaining drugs by fraud. A judge set bail at $35,000.

An arrest warrant affidavit states Benavides offered to pay a woman he was supplying with the anxiety drug Xanax the $2,000 she needed to buy her mother's 1993 Nissan sedan.

Discussing the deal at lunch Nov. 30, Benavides said he would exchange money for sex and the woman reportedly agreed and took the money, the affidavit states. But the next day, she sent him a text message saying she had changed her mind and that she'd reimburse him using her income tax refund, police said.

The woman then allegedly changed her phone number, and on Dec. 1, the woman heard the Nissan's alarm sound at her Universal City home in the 400 block of West Wright, but thought nothing of it, the affidavit states.

Later, she walked outside to find the car on fire. Benavides was arrested without incident around 9:30 p.m. Wednesday.
