The lawyer representing a man and his elderly father who were beaten by a Portuguese police officer says she has filed complaints accusing the officer of aggravated physical assault.

The alleged offenses carry a combined maximum sentence of eight years in prison.

Lawyer Sonia Carneiro told the AP on Friday the two complaints are on behalf of Jose Magalhaes and his 66-year-old father.

Live video of the officer beating Magalhaes with a truncheon outside a Portuguese soccer stadium Sunday, and also punching his father, triggered a scandal in Portugal.

Magalhaes's sons, aged 9 and 13, witnessed the incident but were not hurt.

The police, the public prosecutor and the government have all opened investigations into the officer's conduct.
