A decorated city EMT was ordered held without bail after pleading not guilty today in three Brooklyn sex attacks, including one on an 11-year-old girl.

Angus “Ricky” Pascall, 33, allegedly used a firefighters’ key to stop an elevator he and the 11-year-old were riding on July 11.

In another attack on Tuesday, Pascall, of East Flatbush, allegedly assaulted a 19-year-old woman by forcing her at gunpoint into a car.

Pascall is also charged in a May 21, 2009 assault on a 20-year-old woman at knifepoint in an elevator.

Investigators have DNA evidence in at least two of the three cases, say prosecutors. Pascall is also a suspect in two more cases, but hasn’t been charged yet.

Pascall entered his plea in Brooklyn Criminal Court. His lawyer, John Burke, said the charges are based on the victims picking him out of police lineups. “People are pointing fingers,” he said.

Authorities believe Pascall’s first attack may have been in 2001 — and that he waited eight years before he struck again last year.
