Officials said they had zeroed in on the suspects but declined to reveal their identities, citing ongoing investigations. The “sabotage” was detected during an inspection on Wednesday. Around 64 hollow circular poles and fencing panels, along with some other accessories, were ripped and yanked off, the officials said.The damage has raised serious questions about vigilance and effectiveness of forces patrolling the border. The previous such breach was detected in Aug this year. The Centre has undertaken extensive efforts to secure the Myanmar frontier, with Border Roads Organisation (BRO) carrying out fencing across vulnerable stretches.An FIR was filed over the latest breach. Security has been tightened in the area.
