Boston Bombing suspect's sister arrested over bomb threat

NEW YORK (NEWSCHANNEL 3) - Boston Marathon bombing suspect Dzhokhar Tsarnaev's sister has been arrested after threatening to bomb a New York City woman.

Police say Ailina Tsarnaeva made the threat over the telephone Monday.

She turned herself in Wednesday.

She's charged with aggravated harassment.

Tsarnaeva has been required to check in with Massachusetts probation officers since last October after prosecutors say she did not cooperate with a counterfeiting investigation.
