Two Dearborn men found videotaping the Ambassador Bridge are in custody on a dangerous weapons charge.
Detroit Police spokeswoman Bernadette Najor says officers saw the men during a routine patrol at about 10:00 p.m. Sunday night.
Officials aren't releasing their names, but they say one man is 26 and the other is 30.
The men are being questioned by the FBI.
Najor says they're facing the felony charge because officers found a collapsible baton inside their car. The baton is similar to one carried by police.
Officials are still evaluating whether they should face further charges for carrying two quarter-sticks of dynamite.
The Ambassador Bridge is the nation's busiest international border crossing with Canada.
