More details in the case of a suspected ISIS attack on a U.S. college in Texas, but officials are still trying to figure out who may have carried it out.
The FBI is asking for the public’s help to find the attacker who may be responsible for Monday’s explosion at Denison University in Fort Worth, Texas, where a large blast was heard in the early hours of Monday morning, officials said Tuesday.
The school, located in the state capital of Austin, was evacuated and is now on lockdown.
It is not clear if any of the injured were from Denison, a community of about 6,000 about 80 miles northeast of Dallas.
The campus is also about 45 miles from Fort Worth.
Officials said a white male with a mask and gloves was seen leaving the area.
He may have been in the area and then stopped to buy gas for a friend, according to investigators.
He was seen walking in a nearby parking lot with a small group of people and then heading back to the area where the blast occurred, a law enforcement official told ABC News.
A bomb squad was called in, but no explosives were found, said Capt. Brandon Martin with the Texas Department of Public Safety.
The bomb squad is now assisting with the investigation.
A U.K.-based university said Tuesday it is investigating whether a student who was on campus when the explosion occurred was the perpetrator, but it is not yet clear if he was the attacker.
“It’s still under investigation,” said the university, which is located in London, England.
It was not immediately clear whether the U.KS.-based school, which offers bachelor’s degrees and master’s degrees in law, criminology and education, was the target of the blast.
“The university is aware of the concerns raised regarding the safety of students and staff and we are urgently conducting an investigation to understand what happened on campus,” a statement said.
The university said it has no plans to cancel classes until further notice.
The U.N. Security Council is to hold an emergency meeting later Tuesday to discuss the incident.
The U.G.N.’s emergency meeting is scheduled for Tuesday at 2:30 p.m.
(8:30 a.m., EDT).
