The window panes of Vande Bharat Express were damaged in an alleged stone-pelting by miscreants, between Thalassery and Mahe around 3.30 p.m. on Wednesday.
The alleged incident comes just two days after a similar one between Kannur and Kasaragod.
The attack reportedly took place after the train left at 2:30 p.m. from Kannur. The window panes of the C-8 coach were damaged in the incident.
