A survivor of an alleged Philippine police raid that killed four other drug suspects has asked the Supreme Court to stop such operations and help him obtain police records to prove his innocence in a test case against the president's bloody crackdown.

Lawyer Romel Bagares says his client Efren Morillo, a survivor of the August police raid in Payatas village in metropolitan Manila, and other petitioners also asked the court to order police to stop threatening witnesses.

Bagares says four policemen shot Morillo and four other men whom they accused of being drug pushers. Morillo survived and denied police allegations that he and his friends were drug dealers or that they fought back during the raid.
