Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 32

Sanskrit:

तं निगृह्याच्युतो दोर्भ्यां पातयित्वा महीतले ।पश्यतां दिवि देवानां पशुमारममारयत् ॥ ३२ ॥

ITRANS:

taṁ nigṛhyācyuto dorbhyāṁpātayitvā mahī-talepaśyatāṁ divi devānāṁpaśu-māram amārayat

Translation:

Lord Acyuta clutched Vyomāsura between His arms and threw him to the ground. Then, while the demigods in heaven looked on, Kṛṣṇa killed him in the same way that one kills a sacrificial animal.

Purport:

The ācāryas inform us that sacrificial animals were killed by means of strangulation.
