Ludhiana: GADVASU Teachers' Association (GADVASUTA) suspended OPD services today from 10 am to 12 noon. The protest was in context to malafide FIR registered against GADVASU teacher under the influence of high ranking judicial official. The actual case pertained to death of dog during handling by his own guards. High ranking official rather than blaming his own guards, misused his official powers and defamed attendee teacher and the prestigious institute.
