The three agents were benched for "disciplinary reasons," said Secret Service spokesman Ed Donovan yesterday, declining to elaborate.
Donovan said the incident was prior to Obama's arrival on Monday in the country and did not compromise the president's security in any way.
Still, the incident represents a fresh blemish for an elite agency struggling to rehabilitate its reputation following a high-profile prostitution scandal and other allegations of misconduct.
An inspector general's report in December concluded there was no evidence of widespread misconduct, in line with the service's longstanding assertion that it has no tolerance for inappropriate behaviour.

One agent was discovered highly intoxicated by staff at a hotel, who reported it to the US Embassy, said a person familiar with the situation, who wasn't authorised to discuss the alleged behaviour on the record and demanded anonymity.
The other two agents were deemed complicit because they didn't intervene despite being in a position to assist the drunken agent or tamp down his behaviour, the person said.
Obama arrived in the Netherlands early Monday on the first leg of a weeklong, four-country trip. He departed for Brussels on Tuesday night, and there were no known security issues during his stay in the Netherlands.
