STAMFORD - In the wake of Osama bin Laden's death on Sunday, local security has been heightened over fears of retaliatory attacks. One area for the boost has been on mass transit, and a new K-9 security unit is patrolling commuter trains along the New Haven line.

Gov. Dannel Malloy (D-Conn.) introduced the new Connecticut State Police Mass Transit K-9 Security Unit just last week, and state police say the timing is perfect, with the increase of security over the past few days. As a result, police, troopers and dogs are providing extra security for MTA commuters.

The dogs are trained to find explosive devices, and routine checks are done of train stations and baggage areas. Officers also ride the trains during peak commute times. Passengers say they're happy and comforted to see the heightened security, especially with the concern over retaliatory attacks.

Buses and bus stops are also being patrolled, and the extra security units are expected on ferries soon as well. Police say there has been no direct threat made to Connecticut's mass transit system.
