Watergate

As reported in The Washington Post in 1972:

Five men, one of whom said he is a former employee of the Central Intelligence Agency, were arrested at 2:30 a.m. [Saturday, June 17] in what authorities described as an elaborate plot to bug the offices of the Democratic National Committee here.

Three of the men were native-born Cubans and another was said to have trained Cuban exiles for guerrilla activity after the 1961 Bay of Pigs invasion.

They were surprised at gunpoint by three plain-clothes officers of the metropolitan police department in a sixth floor office at the plush Watergate, 2600 Virginia Ave., NW, where the Democratic National Committee occupies the entire floor.

There was no immediate explanation as to why the five suspects would want to bug the Democratic National Committee offices or whether or not they were working for any other individuals or organizations.
