MUMBAI, Feb 27 (Reuters) - India's Punjab National Bank
(PNB) PNBK.NS said the amount of fraudulent transactions
involving the bank could go up by about $204 million in addition
to the $1.77 billion it had earlier reported, sending shares
down as much as 8.9 percent to a 20-month low.
PNB's announcement late on Monday also sent other shares of
state-run lenders lower, reinforcing concerns about the
escalating financial cost of the unauthorised loans steered
towards billionaire jewellers Nirav Modi and his uncle Mehul
Choksi, owner of Gitanjali Gems Ltd GTGM.NS . L4N1QD2DQ
The scale of the fraud, the biggest to hit an Indian lender,
has stunned the country and put the lack of supervisory
oversight by the central bank and auditors under the spotlight.

Local media reported on Tuesday the Central Bureau of
Investigation, the country's federal police, had raided the
offices of law firm Cyril Amarchand Mangaldas, which had
represented Nirav Modi for a while.
Cyril Amarchand did not immediately respond to a request for
comment, while a CBI media official was not immediately
reachable.
Alpesh Mehta, deputy head of research, Motilal Oswal
Securities, said markets were still trying to determine the
scale of the financial impact since other lenders had given
loans to Modi and Choksi based on letters of undertaking (LOUs),
or guarantees, provided by PNB.
"People would have never expected these kind of losses in a
state-owned bank and it's difficult to ascertain the amount of
damage it has caused," Mehta said referring to PNB.
At least a dozen people - six from the bank and six more
from Modi's and Choksi's companies - have been arrested, while
investigators have seized a number of properties from the two,
including jewellery and luxury vehicles. urn:newsml:reuters.com:*:nL4N1QB2XZ
Both Modi and Choksi, whose whereabouts are unknown, have
said they are innocent. urn:newsml:reuters.com:*:nL4N1QE0AR
PNB shares were trading down 8.2 percent at 0500 GMT, after
earlier hitting its lowest since June 2016.
A sub-index of state-run lenders, the PSU Bank index
.NIFTYPSU , was down 2.5 percent, while top-ranked State Bank
of India was down 2 percent.
