An Albany father has been arrested on suspicion of using a stun gun on his 18-month-old son.

The boy's mother reported the abuse to Albany police.

Investigators say the 21-year-old mother brought her son to the Albany Police Department Saturday. She told police that her husband, 23-year-old Rian Whittman — had been using a stun-gun device on her son.

Police say they discovered Whitman had used the stun-gun many times on the toddler over about a three-week period.

The child's injuries were treated at Samaritan Albany General Hospital. He was then taken into protective custody by the Department of Human Services.

Albany Police arrested Whittman on charges including three counts of assault.

Captain Eric Carter says the device isn't a Taser weapon but an older model that's applied directly to the skin.
