Detroit law enforcement officials have called more officers to duty and moved some to locations deemed higher priorities following the deadly attacks in Paris.
Detroit police Chief James Craig tells The Associated Press Saturday there are no specific or credible threats to his city or others in the U.S. But the department is on "heightened alert" because "you can't always predict the next target."
He said the department has shifted personnel "to soft and hard targets." He wouldn't discuss what he meant by those targets, but Detroit has three casinos, three professional sports arenas or stadiums and an entertainment district.
Detroit also shares a border with Canada. It's one of the busiest trade crossings in North America.
The terror attacks Friday in Paris have killed at least 129 people.
