NEW HAVEN, Conn. (AP) - Police say some saffron finches seized in an alleged bird fighting ring in Connecticut had sharpened beaks and at least one had a sharp metal object attached.

Investigators said in an arrest affidavit unsealed Thursday that they found superglue, antibiotics, skin and blood supplements, a mini digital scale and other unknown powders that are being tested. Shelton police say they believe the materials were used to treat injured birds and increase their stamina to fight.

Police said they found evidence some of the beaks were ground to a point.

Police arrested 19 people from Connecticut, Massachusetts and New Jersey and seized 150 birds in a house raid last month.

The homeowner denied the charges, saying he had the birds for singing.
