Shkreli apologized for his larks in a letter to the judge:

"I wanted to personally apologize to this Court and my lawyers for the aggravation that my recent postings have caused… I understand now that some may have read my comments about Mrs. Clinton as threatening, when that was never my intention when making those comments." A federal judge on Wednesday is scheduled to hold a hearing on whether to revoke Shkreli's $5 million bond after prosecutors complained that he had become a "danger to the community." Even though he was acquitted on five of the eight counts he faces, his increased antics, including his harassment of journalists and the offer of $5,000 for whoever would get him a strand of Hillary Clinton's hair from her book tour, has gotten him in trouble. Will pay $5,000 per hair obtained from Hillary Clinton.”

According to the prosecutors, “Since his conviction on August 4, 2017, Shkreli has engaged in an escalating pattern of threats and harassment that warrant his detention pending sentencing.”

They also said the Secret Service had to invest additional resources out of fear that his fans could take him up on the offer and attempt to snatch Clinton’s hair.
Former businessman Martin Shkreli has his bail revoked for threatening former politician Hillary Clinton, after Shkreli posted on Twitter that he would offer $5,000 to anyone who could directly obtain a lock of Clinton's hair. Shkreli was convicted of fraud in August and is awaiting sentencing.
