Tirupati: In yet another case of disproportionate assets case, an assistant engineer at SV University's engineering division was arrested on Thursday after ACB raided his houses in Tirupati, Nellore and other places on Wednesday.

ACB sleuths found documents of properties owned by Rudrakumar and his family members, and also unaccounted cash and jewellery at his house. The worth of the already seized properties is far beyond his known sources of income, an ACB official said.

Three bank lockers belonging to Rudrakumar were opened this morning.
