Delhi Police — overspeeding challan @ 67 km h with limit @70 mph

Address: 110092

I have been issued challan by delhi traffic police for over speed compounding rs. 400/- per challan (Vehicle no. Dl4c ay 4848) on 8th august at carriageway from akshardham to sarai kale khan near just before yamuna bridge towards ring road and carriageway from sarai kale khan to akshardham near just after yamuna bridge towards akhshardham

But as per picture captured by the camera, i was driving at the speed of @ 67 kmph. Whereas, the display boards on the same road shows speed limit of car as 70 kmph.

The concerned authority may kindly look into the matter and justify my e-challan/notice and withdraw it.
