The message said more details would follow. In a followup tweet, the police department emphasized that “there is no threat to public safety.”
Dzhokhar Tsarnaev, 19, has already been charged in connection with the April 15 bombing that killed 3 people and injured more than 260.
Tsarnaev, whose 26-year-old brother Tamarlan died in a shootout with police three days after the bombings, is being held at a prison medical center in Massachusetts.
U.S. law enforcement officials have been trying to determine whether Tamerlan Tsarnaev was indoctrinated or trained by militants during his visit to Dagestan, a Caspian Sea province that has become the center of a simmering Islamic insurgency.
The security official with the Anti-Extremism Center, a federal agency under Russia’s Interior Ministry, confirmed the Russians shared their concerns. He said that Russian agents were watching Tsarnaev, and that they searched for him when he disappeared two days after the July 2012 death of the Canadian man, who had joined the Islamic insurgency in the region.
The official spoke only on condition of anonymity because he was not authorized to speak to the news media.
Security officials suspected ties between Tsarnaev and the Canadian – an ethnic Russian named William Plotnikov – according to the Novaya Gazeta newspaper, which is known for its independence and investigative reporting and cited an unnamed official with the Anti-Extremism Center, which tracks militants. The newspaper said the men had social networking ties that brought Tsarnaev to the attention of Russian security services for the first time in late 2010.
