Sgt. Kerry Hazelhurst says the body is no longer in Worcester and is now entombed.
Police did not disclose where the body was taken.
Tsarnaev's body had been at the Graham Putnam & Mahoney Funeral Parlors for a week. Director Peter Stefan says he could not find a community willing to take the body, including Cambridge, where the family had lived for a decade. Tsarnaev's uncle, Ruslan Tsarni, had custody of the body.
