Bomb threat fails to halt Detroit Tigers game

(CBS/AP) DETROIT - Baseball stadium Comerica Park is the latest Detroit landmark to be the subject of a bomb threat.

Police say an anonymous caller issued the threat in a 911 call around 8 p.m. Tuesday as the Tigers were hosting the Los Angeles Angels in front of 34,000 fans.

No announcement was made, nor was there a call for an evacuation as police searched the ballpark for an explosive device.

Detroit police Sgt. Eren Stephens says no device was found.

The threat followed two similar incidents in less than a week that shut down a tunnel and a bridge connecting Detroit and Windsor, Ontario, for hours.

On Monday, the Ambassador Bridge was closed for roughly five hours after Detroit police received a 911 call pertaining to a bomb on the international bridge, CBS Detroit reported. The caller reportedly said a bomb would go off in 10 minutes along the busy freight crossing. The bridge was reopened after sweeps failed to turn up any incendiary devices.

Just four days earlier, a bomb threat to police in Windsor led to a four-hour closing of the Detroit-Windsor Tunnel. In this case, Canadian authorities were contacted by an anonymous caller from a pay phone in Windsor. Nearby freeways were also closed and the U.S. Coast Guard was stopping boats and freighters from traveling near the tunnel. Officials reopened the tunnel after sweeps proved the threat a hoax.
