Authorities investigated a "possible pipe bomb" discovered in Boston's South Station on the anniversary of last year's Boston Marathon, Boston.com reported.
The Massachusetts State Police said they detonated the suspicious object -- determined to be a high voltage fuse that fell off a utility truck -- as a precaution. Additionally, all highway ramps that were closed during the investigation have been reopened.
The office of State Fire Marshal Stephen D. Coan released a statement following the discovery, describing the device as a "possible pipe bomb." It also said an investigation by several law enforcement agencies was underway.
"The item was rendered safe,'' the statement said. "Search of the area revealed an identical item clearly labeled high voltage fuse. Closer examination of the first item that had no label revealed it was also a high voltage fuse. It is believed the items came off of a utility truck.''
According to Boston.com, a state trooper found the object and reported it.
As the one-year anniversary of the Boston Marathon bombings is remembered, supporters have come out in full gear to show their support for the victims, their families, and race participants. President Barack Obama also released a statement on this year's marathon.
"A year ago, tragedy struck at the 117th Boston Marathon. Four innocent people were killed that week, and hundreds more were wounded. Today, we remember Krystle Campbell, Lingzi Lu, Martin Richard, and Sean Collier. And we send our thoughts and prayers to those still struggling to recover.
"We also know that the most vivid images from that day were not of smoke and chaos, but of compassion, kindness and strength: A man in a cowboy hat helping a wounded stranger out of harm's way; runners embracing loved ones, and each other; an EMT carrying a spectator to safety. Today, we recognize the incredible courage and leadership of so many Bostonians in the wake of unspeakable tragedy. And we offer our deepest gratitude to the courageous firefighters, police officers, medical professionals, runners and spectators who, in an instant, displayed the spirit Boston was built on - perseverance, freedom and love.
"One year later, we also stand in awe of the men and women who continue to inspire us - learning to stand, walk, dance and run again. With each new step our country is moved by the resilience of a community and a city. And when the sun rises over Boylston Street next Monday - Patriot's Day - hundreds of thousands will come together to show the world the meaning of Boston Strong as a city chooses to run again," the president said.
