Police said, Ashwin, an advocate by profession, had been complaining that parking of lorries, in which water was being supplied to the hill town by one Meenakshisundaram, has been causing inconvenience, as the vehicles blocked the pathway to his house and office at Kunda here.
As Meenakshisundaram continued parking the lorries, Ashwin sought permission from the district administration to use an earthmover to clean his premises, and allegedly demolished the lorry shed belonging to Meenakshisundaram.
One Vignesh, who was sleeping in the shed was caught in the debris and sustained serious injuries, they said, adding, he has been admitted to hospital.

Ashwin, his father and the goons were arrested, Town DSP, Manikandan said, adding, they have been remanded to judicial custody.
