Nobody was injured in the overnight attack, the second on the
agency's offices this week, police said on Friday. It was not clear
who threw the grenades. Supporters of Prime Minister Yingluck
Shinawatra have been demonstrating at the building this week.
The National Anti-Corruption Commission is examining the alleged
failure of Yingluck to stop corruption and stem huge losses in a
government rice-buying program.
It is widely expected to recommend her impeachment by the Senate. If
the Senate takes up the case, Yingluck will have to step aside, with
a deputy prime minister expected to take over. If she is found
guilty by the Senate, she has to step down.
Her supporters, who have been restrained during five months of
anti-government protests in the capital, are starting to mobilize
and are planning their own big rally, or series of rallies, on April
Anti-government demonstrators resumed street protests on Monday

The political paralysis is hurting the economy.
Data on Friday showed factory output fell 4.42 percent in February
from a year before, the 11th fall in a row.
And although customs data on Wednesday logged a 2.4 percent rise in
exports in February compared with a year before, imports plunged
16.6 percent after a 15.5 percent drop in January, showing the
weakness of domestic demand and the reluctance of industry to invest
