Five masked young men robbed a Chinatown bus company’s office at gunpoint on Sunday afternoon, binding five people with duct tape and fleeing with thousands of dollars in cash, the police and the company’s president said.

The robbery occurred at 15 Division Street, at the offices of Golden Express Company, one of several low-cost bus lines in Chinatown that take passengers to and from Atlantic City.

The president of the company, May Chow, said the five men burst into the third-floor office shortly after 12:30 p.m.

“There were these five guys, five young fellows wearing ski masks,” Mrs. Chow said. “One of them jumped over the counter and said: ‘This is a holdup, I’m not kidding. Where is the safe?’ I told him there is no safe in the office. He said, ‘Where is the money?’ I went back and got money from my bag.”

Mrs. Chow said the robbers spotted envelopes with the weekend’s earnings and took them. “They took our sales,” she said. “Three days’ worth. We haven’t really gotten the total yet, but it’s more than $27,000.”
