The balloon was found in the field of Simarjit Singh in Bhagtana Boharwal along the Indo-Pak International Border, who informed the police.
A police party, jointly led by DSP Dera Baba Nanak Surinder Pal Bansal and SHO Jarnail Singh, visited the spot and took the balloon in its custody.
A slip was found along with the balloon in which the names of two Pakistani nationals and three mobile numbers were written, police said.
Police suspected that the balloon might have been sent by Pakistani peddlers to their Indian counterparts.
