Security measures tighter for Michigan football game on Saturday

Security will be tighter at Michigan Stadium on Saturday for the Indiana at Michigan football game.

The Michigan Department of Public Safety said in a release Wednesday that no bags of any size will be permitted for the noon game unless there is written permission from a medical professional. Also prohibited: purses, lunch sacks, binocular cases, fanny packs and diaper bags.

The heightened security comes in wake of warnings this week that terrorists may be targeting entertainment venues, including stadiums.

The counterterrorism bulletin obtained by The Associated Press on stadiums notes that an al-Qaida training manual specifically lists "blasting and destroying the places of amusement, immorality, and sin... and attacking vital economic centers" as desired targets of the global terror network.

After this weekend, Michigan’s next home game is Oct. 17 against Delaware State, and the bag ban may or may not be in place, University police spokeswoman Diane Brown said.

“It’s too early to tell,” she said. “We will re-evaluate before (that game).”

University officials are encouraging fans to get to their seats early, and the university release said increased security likely would cause longer lines. Stadium gates will open at 10 a.m.

To keep lines moving, officials are asking fans to only bring identification, tickets or credentials to the game. Binoculars are allowed if worn around the neck and out of the case. Non-pocket cushions, cell phones and clear, sealed water bottles are permitted, the release said.
