Terming the incident of protest against Cabinet Minister Tota Singh in the US as highly unfortunate, Pujnab Chief Minister Parkash Singh Badal on Monday said that such incidents harmed the interests of the State. He said the people who were not aware of the ground realities were indulging in such activities, which was totally wrong, adding, Punjab had already suffered a lot due to such incidents. “Do the supporters want to bring back the black days in the State,” asked Badal.
