SYDNEY, Aug 1 AAP - A Bangladeshi refugee who is accused of groping a blind woman's breasts on a Sydney train may have assaulted others, a court has heard.

Rubel Sheikh, 25, applied for bail at Parramatta Local Court after he was charged with twice indecently assaulting a young blind woman while she was travelling on a Sydney train last month.

Prosecutor Louise Cummings told the court Sheikh was a refugee who had only been in Australia for a month.

"It's a strong prosecution case, most of it has been captured by CCTV," Ms Cummings told the court on Thursday.

"There's a strong likelihood, if convicted, that he would face a custodial sentence."

She described Sheikh as a flight risk and said three other alleged victims had come forward as a result of the widespread media coverage.

Ms Cummings said Sheikh's immigration status is being investigated, he arrived to Australia by boat and was on a temporary visa.

Sheikh's lawyer Jeff Tunks said he had no family or support network in Australia, spoke little English and had told him he was here on a tourist visa.

A public tip-off led to his arrest after police released CCTV footage of the 23-year-old woman, who told police she had been touched on her breast in an lift at Ashfield, in Sydney's inner west, on July 17.

She later felt a hand on her breast while she was on a train in the city's south, between Jannali and Sutherland railway stations.

Magistrate Les Brennan, who refused bail, said it was an unusual assault.

"This young lady has been followed a great distance," he said.

"Much of the time unaware what's going on because of the disability."

The case will return to Central Local Court on August 6.
