OKLAHOMA CITY -- Some metro Chili's restaurants are wrapping up their first of four "Officer Chad Peery Nights", which raise money to help with his medical costs.

Chili's in Edmond, Midwest City, Yukon and one near Quail Springs Mall are donating 10 percent of their proceeds to Officer Peery.

Prosecutors say three men attacked Officer Peery in February, 2011, when he tried to break up a fight at Dan O'Brien's Pub in Oklahoma City. Peery suffered a severe spinal cord injury, and was left paralyzed from the neck down.

The next Chad Peery Nights are October 23 and 30 and November 6, from 4 p.m. to 10:30 p.m.
