Merced, Calif. Police Department has launched an internal investigation after a black man was brutally beaten and injured while in custody. William Colbert’s arrest photo shows the 39-year-old’s face bloodied and bruised, one of his eyes swollen shut. “I have spoken with Mr. Colbert and collected all the statements about what he said had transpired,” Police Capt. Bimley West said on Wednesday, according to the Merced Sun-Star. “This is a formalized internal affairs investigation into this particular matter.”

To make matters even worse? Colbert says that his arrest and subsequent injuries were all caused because a store clerk decided to call the cops on him because he demanded a refund.

The incident occurred back on March 12.
