Miami Beach police officers arrested a man accused of threatening to kill US President-elect Donald Trump in a video posted on Twitter, official sources said. The man, identified as Dominic Joseph Puopolo, 51, was arrested on Tuesday after posting the video the day before. Puopolo posted a video on his Twitter account that said, "This is the 16th of January 2017. I will be at the review/inauguration and I will kill President Trump, President-elect Trump today".

Miami Beach police said Puopolo was arrested for the crime of threatening a public servant.

He was detained after leaving Subway sandwich shop on Washington Avenue. According to a local affiliate of ABC "Local 10”, he admitted to the agents, in a statement, that he made the Death threats against Donald Trump.

According to records from Miami-Dade Department of Corrections, Puopolo was booked into jail shortly before 4 p.m. Tuesday. No attorney information was available. Puopolo was later taken to the Turner Guilford Knight Correctional Center.

Is he mentally ill?

During a first-appearance court hearing Wednesday, his defense attorney told Miami-Dade County Judge Mindy Glazer that his client is mentally ill. The judge ordered, then, that Puopolo should have a mental evaluation before his bond is set.

According to Miami Herald, Puopolo's mother, Sonia Morales Puopolo, died in the Sept. 11, 2001, terrorist attacks. She was on the American Airlines Flight 11 that crashed into the North Tower of the World Trade Center. It was Hillary Clinton, Trump's opponent in the presidential elections, that delivered the eulogy at the funeral of Puopolo’s mother.

Trump takes office as US president on Friday. It’s expected a very high security at the presidential inauguration. Traffic in the area will be restricted, and roads will be closed starting January 19th, a day before the inauguration.

Death threats were made before

This is not the first time that someone makes a death threat against Trump since the billionaire was announced as the US Presidential election winner. On December, a Florida man was arrested after threatening the life of President-elect Donald Trump on Facebook. The man was identified as Kevin Keith Krohn, 59.

Krohn posted on Facebook “I'm just glad Obama didn't take all our gunz! I see a good use for one now” with a picture of Donald Trump. He also posted a photo of a man holding a sniper rifle and wrote "The EXPEDITER of Trump! He will never last long!”
