Venezuelan authorities ordered the arrest of a close aide to opposition leader Henrique Capriles and military agents searched the man's apartment, the opposition said, calling it proof of a new wave of political repression.

The highest court, meanwhile, rejected Capriles's challenge to the results of the 14 April presidential election in which he narrowly lost to ruling party candidate Nicolás Maduro. The court also fined Capriles US$1,700 for what it called a "disrespectful" filing and told the attorney general that the opposition leader should be prosecuted for his petition.

The 12-party MUD opposition coalition did not elaborate on the government's stated reason for issuing the arrest warrant for Oscar Lopez, the chief of staff to Capriles in the Miranda state governor's office.

Maduro had announced earlier on Wednesday that the government "today captured a chief of the corruption and of the mafias of the Venezuelan right". He did not identify the person but said "he was caught red-handed".

The Associated Press telephoned the chief prosecutor's office but it had no immediate comment.

The Globovision TV network said Lopez's apartment was searched by agents of the military's counter-intelligence agency.

MUD, in the statement announcing the arrest order, called it part of "a new attack against those who don't stop fighting for the restitution of legality, justice and rights in Venezuela".

It charged that the arrest order was part of a strategy to divert attention from Venezuela's problems, among them rampant crime that includes one of the world's top five homicide rates according to the UN and crippling inflation that the government said this week is running at an annual rate of 42.6%.

Venezuela's supreme court on Wednesday threw out Capriles's challenge to the election results. Capriles claims Maduro secured the 1.5-point victory through fraud after squandering a double-digit lead in the polls.

The court's constitutional chamber declared it was "unacceptable" for Capriles to seek the invalidation of the entire vote. It fined him 10,700 bolivars for the "offensive content" and "disrespectful terms" of his court filing and said prosecutors should investigate whether Capriles was criminally liable for trying to undermine the credibility of the election.

Capriles on Wednesday called Maduro "a huge coward" on Twitter for going after his aide and said "millions and millions will run you out of Miraflores [Palace]. Nothing will save you from when we apply the Constitution!"

In recent weeks the government has stepped up pressure on several key opposition members. It announced its intention to freeze the bank accounts of the Miguel Henrique Otero, publisher of El Nacional, one of Venezuela's two remaining nationally circulated newspapers.

Authorities jailed and froze the assets of the editor of a small independent paper and website, Leocenis Garcia of Sexto Poder, who has published detailed reports of alleged government corruption, including what he calls multi-million-dollar graft involving manipulation of currency controls.

The National Assembly, controlled by allies of Maduro, stripped opposition lawmaker Richard Mardo of immunity from prosecution, opening the way for the government to pursue a tax fraud case against him. The opposition calls it a trumped-up attempt to silence a critic.

The late July vote by lawmakers drew especially vehement reproach from the opposition because the constitution specifies that a two-thirds vote is required in the National Assembly to strip a deputy of immunity and the ruling socialists fell 12 votes short of that threshold in the 165-seat chamber.

The opposition and international human rights groups accuse Maduro of trying to crush legitimate, law-abiding dissent by systematically flaunting the socialist administration's control of all branches of government secured under the late President Hugo Chávez.

Maduro accuses the opposition of conspiring with foreign agents led by the United States to overthrow a democratically elected government.

He denied on Wednesday that his government was persecuting opponents. All cases against opposition members were based on "serious investigations, with evidence", he said.
