BEND, Ore. -

A Bend first-grade teacher has been placed on paid administrative leave after his arrest on charges of soliciting a prostitute.

Two Portland women also were arrested on prostitution charges after posting their escort service online and allegedly meeting the man at a northeast Bend motel.

An online ?escort service? listing led Bend police to a northeast Bend motel, where they arrested two Portland women on prostitution charges ? and on Friday, more than a week later, one of their alleged customers, Timothy Caine, was arrested as well, police said Friday.

Bend detectives routinely monitor Websites believed to let individuals post solicitations for prostitution, said Capt. Jim Porter.

On Thursday, March 8, detectives began investigating an Internet listing posted by Athena Renee Dean, 30, and Whitney Blaine Bray-Mackey, 25, Porter said.

Detectives were able to trace the women to the hotel they allegedly were conducting prostitution out of and conducted surveillance, Porter said. In a news release, the captain said the hotel?s identity is being withheld ?due to the ongoing nature of this investigation.?

Around 9 p.m. that night, detectives saw Caine, 44, of Bend, enter the women?s room, stay for a short period of time and leave, Porter said.

Two detectives followed Caine to his home and tried to interview him, while a short time later, detectives contacted Dean and Bray-Mackey in their room.

The women gave police statements, indicating they were actively engaging in prostitution in the Bend area and that ?Caine was only one of their numerous clients? that evening, Porter wrote.

The two women later were arrested for prostitution, but in arrests by citation, meaning they were not jailed, Porter said.

On Friday, Caine also was arrested by Bend police on a prostitution charge, also an arrest by citation, the captain said.

A school district spokeswoman said Caine, who teaches at Jewell Elementary School, has been with the district for six years.

Detectives are trying to identify other suspects who engaged in prostitution with the two women that evening, Porter added.

?The Bend Police Department will continue to monitor Internet Websites that host advertisements for prostitution in the Bend area,? Porter wrote, ?following up with surveillance and arrests of those conducting and participating in prostitution.?
