National shooter Najam, 35, Mubin, 38, Arman, 28, Muzaffar, 45, and Iqbal, 32, were arrested here last night and the carcass of the antelope and her live calf were seized from their vehicle, SP (Rural) Ashok Kumar said.
The firearm used for killing the bull was also recovered, he said.
A case was registered against the five accused under Wild Life (Protection) Act, 1972 and they have been sent to jail, the SP said.
The brother duo was booked by police in February 2012 here for allegedly killing a Sambar deer, he said.
However, Allahabad High Court had stayed their arrest in the case, he said.
