Rep. Conyers wants probe into Detroit-Canada tunnel, bridge bomb threats

An influential House Democrat is calling on the Department of Homeland Security to investigate recent threats against a key tunnel and bridge that connect Detroit and nearby Windsor, Ontario, in Canada.

Rep. John Conyers Jr. (D-Mich.) said Tuesday that a bomb threat against the Detroit-Windsor tunnel on July 12 and a threat against the Ambassador Bridge Monday evening were concerning because the roadways are both heavily used. 

"The Detroit-Windsor Tunnel and the Ambassador Bridge are critical to Detroit commerce, and threats against these crossings are a matter of national concern for both the United States and Canada," Conyers wrote in a letter to Homeland Security Secretary Janet Napolitano. 

Conyers added that the Ambassador Bridge was "the busiest commercial border crossing in the North America," and called for DHS to thorough review the threats.

"I understand various federal agencies, including the Department of Homeland Security, have been working with the Detroit Police Department and Canadian law enforcement to investigate these incidents," Conyers wrote.

"Because of the importance of these international crossings, I ask that you work with local and Canadian authorities to conduct a thorough review of the security measures for the Detroit-Windsor Tunnel and the Ambassador Bridge, and to augment current procedures by developing additional steps to protect them from harm," he continued.
