Police patrol transportation centers

Local law enforcement officials promised heightened security and called for vigilance in the wake of terrorist attacks in New York, New Jersey and Minnesota that left dozens injured.

“We are obviously on a heightened alert,” police Commissioner William B. Evans told Boston Herald Radio yesterday. “Since (Sunday night), our intelligence has been in contact with NYPD and their intelligence. We have been monitoring to see what’s going on.”

Evans said additional police resources have been dispatched around city transportation centers, and BPD has received various tips about possible suspicious people, packages and vehicles.

MBTA Transit Police Superintendent Richard Sullivan also said his department has seen an uptick in alerts from the public. He encouraged the public to continue to speak up if something looks out of place.

“We would rather get 1,000 reports that turn out to be nothing, than to not get that one because the person felt it was foolish and didn’t want to bother us,” Sullivan said. “Any time we experience things like this worldwide, we have an uptick in calls of suspicious people, items, packages. We fully expect it, we are fully prepared for it, that just shows it is working.”

Commuters filed in and out of South Station during rush hour yesterday as transit cops patrolled both inside the terminal and on the platform. Bomb-sniffing dogs weaved around tables outside the food court with their handlers, examining bags on the ground next to riders.
