Ivan Zayd Guillama Rosario Arrested for Making Threats

Special Agent in Charge Douglas A. Leff of the Federal Bureau of Investigation (FBI) San Juan Field Office announced the arrest of Ivan Zayd Guillama Rosario.

On April 28, 2017, law enforcement officers located Guillama Rosario at his place of employment. Guillama Rosario confirmed that he is the owner of the Facebook account Ivan Zayd Guillama Rosario and that he posted “!Vamos a bombardear el capitolio y que en paz descansen nuestras conciencas!” ("We are going to bomb the Capitol and may our consciences rest in peace") on Facebook on the same day.

On April 29, 2017, Guillama Rosario was arrested by FBI San Juan agents and Police of Puerto Rico task force partners at his residence in Camuy, Puerto Rico.

"It is a serious federal crime to use the Internet to transmit bomb threats and other acts of violence, regardless of any cause that the perpetrator is seeking to advocate. It is also an embarrassment to any legitimate group seeking change from the government to have their message associated with someone whose goal is to create violence. For this reason, the FBI will continue to swiftly arrest anyone who uses social media to incite violence, and will deliver the perpetrators to our partners at the United States Attorney’s Office, who are eagerly awaiting the opportunity to prosecute them to the fullest extent of the law." 

If convicted, Guillama Rosario faces a maximum term of imprisonment of 10 years, a term of supervised release of up to three years, and a fine of up to $250,000.

This case is being prosecuted by Assistant United States Attorney Alexander Alum. It is being investigated by the FBI.

The public is reminded that a criminal complaint contains only charges and is not evidence of guilt. A defendant is presumed to be innocent unless and until proven guilty. The U.S. government has the burden of proving guilt beyond a reasonable doubt.
