A Wheaton business owner facing charges in connection with two sexual assaults in the fall has been charged in another attack, Montgomery County authorities said Friday.

Ramon Vasquez, who owns a marketing company that works with doctors and chiropractors, was charged with attempted ­second-degree rape in a May 17 incident, police said. He was charged in January in connection with attacks on two women in November.

In the May incident, Vasquez allegedly invited the victim to his house, drugged her with two sleeping pills and tried to assault her while she slept, according to charging documents.

In the first incident, court records show that Vasquez attended a concert in Hyattsville with two female friends. The three went for drinks in the District and then to Vasquez’s house in Wheaton.

The two women stayed overnight, authorities said, and while they slept, Vasquez allegedly fondled one of them. The woman woke up and left the room, but then Vasquez assaulted the second sleeping woman, according to records.

Both women contacted police, according to a statement released Friday.

Police arrested Vasquez on Jan. 8 and charged him with one count of sexual assault and one of second-degree rape. He posted bond the next day; his trial had been set for Sept. 3.

As a result of the arrest this week, Vasquez is being held without bond.

David Moyse, one of Vasquez’s attorneys, said his client is innocent.

“I can tell you he denies the charges and looks forward to proving himself at court,” he said.
