A Suffolk bank executive and real estate developer has completed 70 hours of community service and expects to have his misdemeanor charge of forcible touching dismissed next month, his lawyer said Friday.

John Tsunis, 64, of Poquott, board chairman and chief executive officer of Gold Coast Bank, resolved the criminal case against him in December, said his lawyer, David Besso of Bay Shore.

Tsunis was charged after a female security worker accused Tsunis of grabbing her buttocks during a Stony Brook University basketball game on March 4, 2015.

In a criminal complaint, the security worker said she had tried to stop Tsunis from trying to use an entryway between VIP suites. He then grabbed her under the armpits and tried to move her aside, then touched her inappropriately after she demanded he release her, according to the complaint.

Besso said his client did nothing wrong and did the community service to ensure he had no criminal record.

“Basically, they had no proof,” Besso said. “He didn’t do anything.”

The Suffolk County district attorney’s office recused itself from the case because Tsunis had contributed to District Attorney Thomas Spota’s campaigns. Attorney Patrick O’Connell of Central Islip was appointed special prosecutor. He did not respond to a request for comment.

District Court Judge Karen Kerr approved the agreement. If Tsunis is charged with a new crime before next month, the forcible touching charge could be reinstated.

Tsunis, also a lawyer, has served as chairman of the Stony Brook Long Island Children’s Hospital Task Force, chairman of the board of trustees of the Long Island Museum in Stony Brook and is a former president of the Three Village Chamber of Commerce. He is also the board chairman of the New York State Hospitality & Tourism Association.
