Phoolka, who recently quit all posts he held in Aam Aadmi Party (AAP) to concentrate on the 1984 anti-Sikh riots cases, said Singh had several times issued statements claiming that his party colleague Tytler was never involved in anti-Sikh riots though the matter was pending in court.
Phoolka said he travelled 30 kms by road, along with his followers, to seek apology from Singh for issuing "wrong statements to please his political bosses".
Congress MP from Amritsar Singh was recently appointed Punjab Pradesh Congress Committee president, replacing Partap Singh Bajwa.
