Washington: An Indian grandfather, who was violently assaulted by an American police officer earlier this year, was slammed to the ground and left paralysed in 101 seconds after encountering police despite pleading five times that he knows no English, a US court has been told.

The retrial of police officer Eric Parker, accused of violently assaulting 58-year-old Sureshbhai Patel that left him partially paralysed, began this week in a federal court in Alabama.
