Three illegal aliens have been arrested by the Border Patrol in two separate incidents at international bridges between Canada and the United States.

Two citizens of Guatemala were captured about 10 p.m. Monday at the International Railroad Bridge between Fort Erie, Ont., and Buffalo while allegedly trying to hide themselves in a freight train coming into the United States. Border Patrol agents said they claimed they were planning to go to Atlanta, Ga.

Patrols at the Whirlpool Rapids Bridge in Niagara Falls spotted a man from Kosova at 4 a.m. Monday. They said the man was wearing dark clothes and trying to conceal himself as he crossed the bridge. They said the Kosovo immigrant was carring some marijuana and a check of records revealed he had numerous criminal convictions in Canada and was the subject of a Canadian criminal arrest warrant.

If illegal aliens are not stopped by Border Patrol agents, they can quickly blend into the general publics in Buffalo and Niagara Falls and obtain transportation to other destinations in this country, spokesmen for the Border Patrol said.

Witnesses can report suspicious activity to the Border Patrol and remain anonymous by calling 1-800-331-0353 toll free.
