WASHINGTON (WUSA9) -- WASHINGTON (WUSA9) – A woman says she was sexually assaulted by three men Thursday night on a Metro train.

Metro police are now searching for three persons of interest connected to the assault.

The alleged attack happened onboard a Yellow line train headed north from Huntington station around 9:30 p.m.

As the victim's train traveled north through Virginia, she says she was approached by three men demanding she perform a sexual act.

When she refused, the victim told police, they assaulted her, groping and grabbing her through her clothes.

This report comes on the heels of several high profile sexual assaults connected to Metro. An alleged April rape on the Red line was made public in May, which led WMATA to change its reporting protocols to the approval of anti-assault and harassment advocates like Jessica Raven.

“I’m glad that there has been a lot of media coverage, because we need to get outraged every single time,” said Raven, Collective Action for Safe Spaces. “Um... that’s the only way to change the conversation and make it clear that this behavior isn’t going to be tolerated.”

Despite other Metro assaults, Raven says WMATA’s efforts at training staff, making reporting easier and raising awareness raise Metro above its peer systems.

"There are a lot of things to complain about when it comes to Metro, but when it comes to addressing sexual harassment they’re doing an excellent job," said Raven. "They’re doing everything that they really can be doing."
