SAN DIEGO -- Chargers defensive back Antonio Cromartie will not face criminal charges in connection with an alleged assault during a rowdy celebration at a Pacific Beach tavern last month, a police spokeswoman said Thursday.

Investigators found no evidence that Cromartie threw a champagne bottle that hit 24-year-old San Diego resident Kamaldeep Saran on the head at Bar West on Hornblend Street about 1:15 a.m. Nov. 22, San Diego Police Department information officer Monica Munoz said.

Saran's injuries were not serious enough to require hospital treatment, and no one was arrested.

At the time of the purported assault, Cromartie and several of his Chargers teammates were at the watering hole celebrating that afternoon's 32-3 victory over the Denver Broncos.

The Pro Bowl star told police the bottle had merely "slipped out of his hand," Detective Gary Hassen said.

A man who was with Saran at the bar told 10News that prior to the purported assault, his group and the professional athletes had been celebrating the team's win by buying bottles of champagne, shaking them up and spraying each other with the wine. The festivities came to an end, the witness said, when Cromartie hit his friend with one of the bottles.

After reviewing a police report on the incident, SDPD Northern Division Capt. Chris Ball decided that there was not enough evidence of a crime to merit sending the case to the San Diego City Attorney's Office or the county District Attorney's Office, Munoz said.
