A 47-year-old San Francisco man was convicted Tuesday of four misdemeanor counts related to a September incident in which he harassed members of a local mosque celebrating Ramadan, according to the district attorney’s office.

Gregory Tolbert, also known as Troy Adams, was found guilty of two misdemeanor counts of battery and two misdemeanor counts of interference with the exercise of civil rights for a Sept. 20 encounter with congregants of the Al-Sabeel mosque, the district attorney’s office said.

Tolbert reportedly showed up at a breakfast reception in Victoria Manalo Draves Park in the South of Market District, where members of the mosque were celebrating the end of the Ramadan holiday.

Prosecutors said Tolbert began shouting racial and ethnic slurs at the celebrants and was escorted out of the park, but returned later in the afternoon and “caused a disturbance” in an area designated for women and children.

As members again asked him to leave, Tolbert began cursing and swung his backpack at one man, injuring the man’s hand, and scratched another man on his cheek and neck, prosecutors said.

He continued to shout racial and religious slurs until police arrived and arrested him, prosecutors said.

“The law will come down hard on those who violate the civil rights of others,” District Attorney Kamala Harris said in a statement Tuesday.

“There is no place in a civilized society for behavior that steals the free exercise and enjoyment of any right or privilege guaranteed by the Constitution,” Harris said.

Tolbert faces a year in county jail, a $5,000 fine and 400 hours of community service at his sentencing today, according to the district attorney’s office.
