The reward would be paid for information leading to the ''surrender, arrest of capture'' of army colonel-turned-politician Gregorio ''Gringo'' Honasan, Interior Secretary Ronaldo Puno told reporters.

A total of P3 million in rewards was also offered for six other suspects, whose pictures appeared in posters to be put up by police in public places around Manila Thursday.

Honasan has been at large since the government named him as a leader of the alleged February 24 plot, which prompted Arroyo to declare a week-long state of national emergency the same day.

Arroyo spokesman Ignacio Bunye said the bounty proved that ''no one, not even a former senator, is above the law.''

''We call on him to live up to his stature as a former senator by voluntarily yielding to police authorities,'' Bunye said.

''The plot against our legitimate government must stop so that our people's lives can be normalized and the country can move forward.''

The plot allegedly called for the ousting of Arroyo and was to have taken place on the eve of the 20th anniversary of a popular revolt that toppled dictator Ferdinand Marcos.

It allegedly was hatched by communist rebels, disgruntled military officers and opposition figures, including Honasan and six leftist legislators. One of the legislators was arrested last month and the five others have sought sanctuary in Congress.

The six who appeared in the wanted poster with Honasan were Navy captain Felix Turingan, a classmate of Honasan in the Philippine Military Academy in the 1970s, and five Honasan aides.

One of the accused Honasan aides, Ernesto Macahiya, said the announcement was a ''classic case of taxpayer's money being spent as bounty for people who are fighting for the people.''

''I cannot get justice under the present administration,'' he told reporters by telephone, admitting that he had gone into hiding.

Arroyo's government had also implicated Honasan in a failed 2003 rebellion by some 300 junior officers and their men who took over an upscale apartment hotel in Manila's financial center.

Charges however were not pursued when Arroyo offered reconciliation to her opponents.
