UPDATE: The suspect was found and taken into custody in the Kalihi area at approximately 12:10 p.m. Tuesday and was placed under arrest for Sex Assault in the Fourth Degree.

Crimestoppers needs help finding a suspect in a sexual assault case that began when he saw a woman on TheBus. 

A spokesman for Honolulu Crimestoppers said after trying to talk to the woman, the suspect followed her off the bus, and sexually assaulted her at Windward Mall.

Crimestoppers released video of the suspect on the bus Monday afternoon. 

"We're hoping someone in the public recognizes him and calls it in," said Sgt. Chris Kim.

After the incident, the woman notified mall security, and then got back on the bus with a friend, where the suspect approached her a second time. 

She told the suspect she was going to contact police. 

"We want our riders to feel safe on the bus, so we just want to remind the public, don't ever be afraid and notify the driver of what's going on," said Sgt. Kim. 

Sgt. Kim said the woman got off at the bus stop next to Castle Medical Center and called police. 

The incident happened on August 2nd, but investigators say 4-months later, the suspect is still on the run. 

"At some point, if they feel like they're at a dead end, they are going to reach out to Crimestoppers and at which time we reach out to the public for their assistance," said Sgt. Kim.  

The suspect is in his thirties to forties, 5'8" to 6' tall, and between 140-160 lbs. 

"The Crimestoppers program is an effective tool," said Sgt. Kim, "and with the public's help, we strongly believe that we can identify this person, and once again, I'd like to remind the public that they are eligible for a reward up to $1000."

If you find yourself in a similar situation on the bus, follow this advice. 

"Stay on the bus, notify the driver, if you have a cell phone, go ahead and call police, call 911 and say you're on this bus number, this route, this location," said Sgt. Kim.  

If the suspect looks familiar to you, call Crimestoppers at 955-8300. You can also text to *CRIME on your cell phone or send anonymous web tips to www.honolulucrimestoppers.org.
