Now for my bit, it is a Bagarius bagarius or a Glyptothorax, I think coheni it is a large growing Indian catfish, below is a picture of it's holotype, USNM 205612, although small this was the first Glyptothorax coheni described,
do they eat people? I some how doubt it unless the body was in an advanced state of decomposition, remember it is a catfish, the teeth that it has are called Pharyngeal teeth, they are situated at the back of the fishes throat, they can grind food but not cut it, also some species of fish can use these teeth to produce a audible grinding sound, the lips of the fish have small file like teeth to rasp at algae but again lack the ability to cut flesh.
Or it could be Bagarius bagarius
Bagarius bagarius is commonly known as the Devil Catfish, which is also referred to as Bagarius yarellii. This catfish is quite a rare find amongst shipments of fish from Asia. Bagarius bagarius belongs to the family Sisoridae which are more commonly referred to as Asian Hillstream Catfishes. Within this group of catfish there are around 23 genera and 85 species. As their family name suggests they are naturally found in the fast flowing freshwaters of southern Asia. Most of the catfish within the family Sisoridae are small to medium in size from 6-30cm, with the exception of Bagarius with representative species growing in excess of 2 metres! The difference with this fish is that as they grow larger the rasping teeth become significantly larger, though still not able to cut through flesh.
