In a message Jammu Police on Saturday said, "Amrik Singh, resident of R S Pura and his wife namely Sarabjeet Kour were detained and further handed over to Punjab Police."
They have been detained for reportedly having links with Papalpreet Singh (a close aide of Amritpal Singh).
According to police sources, the mobile phones of the couple have also been seized for further investigation.
"The matter is being investigated by Punjab Police and they will be questioning the couple in the case," they added.
Papalpreet reportedly had been working with Amritpal closely since he returned to India last year and took over the reins of 'Waris Punjab De', an organisation founded by actor Deep Sidhu, who died in a road accident in 2021.
