MINNEAPOLIS — University of Minnesota is stepping up security on the Twin Cities campus this year.

Students may notice additional police, stricter access to buildings and more discussions about safety. With the Green Line light rail now stopping at the university and increased traffic from the Minnesota Vikings games at TCF Bank Stadium, university officials expect more outsiders will be on campus.

The university will spend $4 million to improve security. A spike in crime in and around campus last fall had students and others concerned. There were 26 robberies in the area — a 50 percent increase over the previous year.
