SAN JUAN, Puerto Rico (AP) — Federal authorities in Puerto Rico have arrested an executive at Pfizer Pharmaceutical for allegedly producing child pornography.

Officials say 48-year-old Reinaldo Diaz Camacho was charged after Puerto Rico police received information that he was having sexually explicit conversations with a 16-year-old boy on Facebook.

U.S. Attorney Rosa Emilia Rodriguez said Thursday that the boy’s mother told authorities she had seen the conversations on her son’s cellphone.

Rodriguez says Diaz had sent the boy sexually explicit images via Facebook and text messages. She says a federal agent then posed as the teen on Facebook and continued to interact with Diaz. She says Diaz asked the boy to send naked pictures of himself.

It was not immediately clear whether Diaz has an attorney.
