FOXBOROUGH — Gillette Stadium is no airport, but it could soon feel like one as heightened security upgrades following the Boston Marathon bombings impose restrictions that stop short of having fans remove their shoes.
The new rules being implemented by Foxborough police, in conjunction with the National Football League, include a ban on backpacks and large purses, in addition to existing bans on coolers and seat cushions.
Only clear plastic, vinyl, or PVC bags that do not exceed 12 inches by 6 inches by 12 inches — and permissible things that fit in them — will be allowed in the stadium after Aug. 16, unless a medical necessity requires a nonconforming bag.
The rules go into effect the day the New England Patriots meet the Tampa Bay Buccaneers in the first preseason home opener. Full story for BostonGlobe.com subscribers.
