New York�s attorney general will investigate the death of an emotionally disturbed man who died after being subdued by a police officer with a stun gun.

A spokeswoman for Attorney General Eric Schneiderman said Saturday that the office has opened an investigation into the death of Ariel Galarza in the Bronx on Wednesday.

Police said the 49-year-old Galarza threatened officers with a bottle before a sergeant discharged his stun gun twice. Galarza went into cardiac arrest and was taken to a hospital, where he died.

Schneiderman�s office has the power to investigate deaths of unarmed people at the hands of police.

Sanford Rubenstein, an attorney for Galarza�s family, called Schneiderman�s decision to investigate the death �a positive first step.�

But Rubenstein said a grand jury should consider bringing criminal charges.
