Families attending this weekend's UMass Dartmouth graduation will see increased police presence and restrictions on what can be carried into the amphitheater as officials grapple with security in the wake of Dzhokhar Tsarnaev's connection to the Boston Marathon bombings.

The University also plans, for the first time, to require family members to have tickets to Sunday's ceremony, limiting graduates to two relatives each. As part of the other increased security measures, the school plans to significantly bump up the number of state and local police along with private security contractors.

Backpacks, briefcases, wrapped presents, laptops and beach balls are banned from graduation. Officials also barred fireworks. The policy does not apply to Saturday's graduate student ceremony.
