Chandigarh, Aug 3 (IANS): Punjab Chief Minister Amarinder Singh on Wednesday called up Karnataka Chief Minister Siddaramaiah to seek his intervention in ensuring justice for a Sikh family allegedly assaulted in Bangaluru.

"Amarinder called up his Karnataka counterpart to express concern over the brazen attack on the family members of retired Sikh army officer, Colonel R.S. Uppal," the Chief Minister's spokesman said here.

Amarinder Singh urged Siddaramaiah to provide protection to the family and to direct the police to arrest the culprits immediately and bring them to book.

The Karnataka Chief Minister assured Amarinder of all support from his government to Uppal's family, the spokesman said.

The Uppal family, which resides in Bangaluru, had alleged that they were recently attacked by some people who were coercing them to sell their property and leave the city.

"Uppal's wife and two sons were assaulted, with his son Harmeet, an IT professional working in the US, left with multiple fractures," the spokesman said.

Uppal alleged that the Bangaluru police failed to provide the family with security despite complaints of threats received earlier from unidentified persons.
