Sebi says investigation into Jane Street could be wider

India's markets regulator on Tuesday said the investigation and final order on Jane Street could be much wider, adding that it will not release any documents that were not relied upon for passing the order in the case.

Last week, Jane Street filed an appeal against the Securities and Exchange Board of India (SEBI), seeking to compel it to release documents the U.S. high-frequency trading firm said were pertinent to rebut allegations of market manipulation.

Hearing for the case kicked off on Tuesday, with SEBI saying the investigation against Jane street is at a critical juncture and is on going.
