A high school student from Massachusetts is being investigated by the police for threatening to carry out a Las Vegas-style shooting at his school on social media.

Reports said the 16-year-old student (who was not identified) of Quincy High School went on a rant on Snapchat and wrote, “You f****** better learn to walk the halls or Quincy high is gonna turn into Las Vegas, except no one will escape,” Fox News reported.

According to reports, police were first made aware of the incident Tuesday after which they began their investigation.

There was no immediate threat to the school, Quincy Police Captain John Dougan said Wednesday, Daily Mail reported. Authorities, however, said they will continue with their investigation and the teen is likely to face charges.

Quincy Schools Superintendent Richard DeChristofaro said parents of students were notified of the situation.

'A student may post something that may be alarming in any way or that may cause our students to have some anxiety or concern and we deal with it appropriately,' DeChristofaro said.

The threat by the student was made just a few days after a shooter killed at least 58 people and injured more than 400 in Las Vegas, in one of the deadliest mass shootings in U.S. history.

The gunman was later identified as Stephen Paddock, a 64-year-old white male, who was found dead in his room on the 32nd floor of the Mandalay Bay hotel.

FBI Deputy Director Andrew McCabe spoke to CNBC on Wednesday and said that the lack of clear motive was a "surprise" in the shooting.

"This one is somewhat different than many of the ones we've dealt with in the past, because we don't have any immediately accessible thumbprints that would indicate the shooter's ideology or motivation, or really what compelled him to get there," he said.

As of now, authorities have already questioned the shooter’s girlfriend, Marilou Danley, after she returned to the U.S. from the Philippines on Tuesday night. In her statement, she said that she didn't know Paddock had planned to carry out the mass shooting.

She described him as a "kind" person who never gave any warning "that something horrible like this was going to happen."

"I loved him and hoped for a quiet future together with him," Danley said in the statement. "He never said anything to me or took any that I was aware of that I understood in any way to be a warning..."

Clark County Sheriff Joseph Lombardo revealed in a press conference Wednesday that authorities found that 50 pounds (22.6 kilograms) of Tannerite (used to make exploding targets for firearms practice and explosive devices) in Paddock’s car as well as 1,600 rounds of ammunition.

The investigators are now trying to find out whether Paddock worked as a lone wolf or was aided by someone to carry out his carnage.
