Classes resumed Wednesday at Northeastern University after a package exploded on campus Tuesday, injuring one person.
Boston police, the FBI and the Bureau of Alcohol, Tobacco, Firearms and Explosives were investigating a possible motive for the incident at the university’s Holmes Hall that canceled Tuesday night classes and closed part of campus.
The explosion brought nearby Harvard University and the Massachusetts Institute of Technology on high alert as investigators worked on another suspicious package located near a major art museum.
Here’s what you need to know about the ongoing investigation.
What happened at Northeastern University?
Boston police responded to Northeastern University’s 16,000-person campus around 7:20 p.m. Tuesday after a suspicious package exploded, the police department said in a statement.
It was delivered to the private university’s Holmes Hall around 7 p.m. and exploded when a staff member opened it, university spokeswoman Shannon Nargi told USA TODAY in an email. Pupils in an evening class at Holmes Hall were evacuated when police and emergency services arrived.
Investigators located another suspicious package at an area art museum on Tuesday evening.
“Boston Police Department Bomb Squad was able to secure the package without further incident,” police said in a statement.
Classes and activities resumed Wednesday after investigators deemed the campus “safe and secure,” university provost David Madigan and chancellor Kenneth Henderson wrote in a joint statement.
Who was hurt?
An unidentified staff member who handled the package was injured, authorities said.
The university provided no update Wednesday on the condition of the staff member, identified by Boston police as a 45-year-old man. His hand injuries were reportedly minor. He was taken to hospital for treatment, authorities said.
There were no other reports of injuries from the package exploding.
What was in the package?
The hard plastic case that exploded contained a rambling note that denounced virtual reality and referred to Facebook founder Mark Zuckerberg, a law enforcement official told The Associated Press. The official spoke to the AP on condition of anonymity and could not publicly discuss details of the investigation.
The package, described by the official as a “pelican-style” case, was specifically sent to the northeast, the official told the AP. Pelican manufactures hard cases designed to protect sensitive equipment.
Authorities were also investigating the specific mechanism of the device and whether the package contained gunpowder, the official said.
Have the police identified a suspect?
Police had no overnight developments as they continued their investigation, Boston Police Officer Andre Watson told USA TODAY on Wednesday.
It is unclear whether police have identified a suspect. The FBI declined to comment further on the case, citing a desire to “respect the integrity of the investigation.” ATF also declined to comment and referred questions to the FBI.
