Again in April 1790, a body of 12,000 Sikhs led by Karam Singh ravaged the Doab including Hapur, 57 km from Delhi, and `Aligarh. Karam Singh sent his vakilto MahadjT Scindia, regent of the Mughal empire, demanding more grants of lands in the Doab. After some time Scindia granted to Karam Singh, Shikarpur in jdgir and the title of Sardar under the royal seal. Karam Singh`s son, Kharak Singh, was married to Prem Kaur, daughter of Raja Sahib Singh of Patiala.
