Russian police pursuing other members of Pussy Riot

* Pressure kept up despite outcry over jailing of 3 members

MOSCOW, Aug 20 (Reuters) - Russian police are searching for

more members of the Pussy Riot punk rock band, a spokeswoman

said, signalling further pressure on the group despite an

international outcry over jail terms for three women who

protested in a church against Vladimir Putin.

The Russian president's critics condemned the court

proceeding that yielded the two-year prison sentences on Friday

as part of a clampdown on a protest movement and reminiscent of

show trials of dissidents in the Soviet era.

Police said on Monday they were searching for other members

of the group over the February protest at Moscow's Christ the

Saviour Cathedral, but had not yet identified the suspects.

Police did not say how many people they were looking for,

nor whether they faced arrest and charges or whether they were

just wanted for questioning.

Although the search was launched before Friday's verdict,

the determination of police to pursue other Pussy Riot members

suggested the Kremlin would keep the heat on the band despite

the furore over the punishment imposed on the three young women.

"The necessary search operations are being conducted," a

representative of the Moscow police told Interfax news agency.

A police spokeswoman in Moscow's central district confirmed

by telephone that other, unidentified members of Pussy Riot were

being sought under a criminal case that was now separate from

the case against the three performers who were tried.

Nadezhda Tolokonnikova, 22, Maria Alyokhina, 24, and

Yekaterina Samutsevich, 30, were convicted of hooliganism

motivated by religious hatred over their performance of a "punk

prayer" urging the Virgin Mary to rid Russia of Putin.

The three held forth in front of the altar and wearing ski

masks to conceal their identity, but were arrested after the

protest. Two others who took part remain at large and the group

has said it planned further demonstrations against Putin.

In an interview last week, other members of Pussy Riot -

their faces hidden behind colourful ski masks like those worn

during the "punk prayer" - said the trial had only strengthened

their resolve.

The United States, European Union and several nations have

called the sentences disproportionate, and the United States has

urged Russian authorities to "review" the case.

Tolokonnikova, Alyokhina and Samutsevich said they had

sought to protest against Putin's close ties with the Russian

Orthodox Church and had not set out to offend believers.

Putin himself, an ex-KGB spy who returned to the presidency

for a third term on May 7 after a four-year spell as prime

minister, said before the sentences were pronounced that the

women did "nothing good" but should not be judged too harshly.

They have already been in jail for about five months,

meaning they will serve another 19, and could be freed if Putin

were to pardon them. The Orthodox Church hinted it would not

oppose such a move by appealing, belatedly, for mercy.

Madonna on Saturday joined a chorus of celebrities in

denouncing the jail terms imposed on the three women. She said

they were being sent to a "penal colony for ... a 40-second

performance extolling their political opinions".
