The ICC on Friday rejected Pakistan's conspiracy theory behind the suspension of three of its players in connection with the “spot-fixing” scandal and said clear indications were given about the impending action.

It also said the three cricketers have a "case to answer" but refused to specify the charges against them. Addressing a press conference here, ICC CEO Haroon Lorgat dismissed a question that the action was taken to keep Pakistan out of international cricket.

"The very reason I met your high commissioner Wajid Hasan was to give a clear indication that we are coming to a conclusion and that we will be serving a notice. I differ with Pakistan high commission interpretation of the meet. I indicated to him about issuing the notice," he said.

Earlier in the day, Mr Hasan attacked the ICC saying it had taken an unethical decision and sought to insinuate that ICC president Sharad Pawar had a hand in it.

After suspending the trio of Pakistan Test skipper Salman Butt and pacers Mohammad Amir and Mohammad Asif, the ICC said after "due diligence", it is clear that the players have to explain themselves following a sting operation in which a bookie claimed to have paid them money for bowling no-balls in a Test match against England.

"The press suggested this week that why didn't the ICC act immediately? There was no specific cause to make us act yesterday. It was about taking legal advice, having teleconferences and examine the case," ICC's Anti-Corruption and Security Unit chief Sir Ronnie Flanagan said in the press conference.

"The conclusion was that it was an arguable case against the players. We certainly came to the conclusion that they have a case to answer to our disciplinary commission," he added.

Mr Lorgat said the ICC would be "decisive" in its action against guilty players but only after establishing their guilt. "We promise to be decisive. We got a week for due diligence. We have got to be very mindful of the interviews that are going on right now with the police.

"Last night was the first opportunity we got in which we concluded what we have done. We needed to do all the evidence gathering and frame charges. We cannot suspend any player without formally charging anyone," he said.

On whether criminal charges would be pressed against the players, who are being investigated by the Scotland Yard, Flanagan refused to comment.

"It would be absolutely wrong for me comment to (on whether criminal charges would be brought). If the police find evidence, it is for the prosecuting authorities to make that decision. We would be absolutely wrong to make a comment on that. It's a complex investigation," Flanagan said.

Asked whether the ICC had failed in its responsibility of educating players about the implications of getting involved in corruption, Flanagan said, "Absolutely not."

"There are many instances where the ACSU has prevented this possibility. I absolutely refute the suggestions that this in anyway shows a failure on the ACSU's part," he added.

The two officials also refused to divulge the specific charges levelled against the players by the ICC. "There are various charges and they all relate to this issue. They know exactly what the charges are. Quite frankly it would not be right for us to specifically state these charges in front of the media," said Mr Lorgat.

Quizzed about the Sydney Test between Australia and Pakistan, which is also suspected to be fixed, Flanagan said the governing body would act according to the evidence available with it.

"There was a particular match in Australia. The ACSU very concisely stated that it was a dysfunctional tour and there were things that went on. We have investigations going on of all kinds. The criminal investigations at this stage are focused on Lord's. We are the investigating agency of the ICC and we will go where the evidence takes us," he said.

"We would be examining all the evidence that will brought forward in this case. We will investigate in any given case. We are in the process of examining and if it takes us back to something we would certainly do that," he added.

Mr Lorgat rejected suggestions that the scandal was just the tip of an iceberg and that there was widespread corruption in cricket. "We can't work on hearsay or speculation. The vast majority of players are honest and on occasions, they are not, we deal with it," he said.

Asked whether “spot-fixing”, which involves rigging events within a match, is widespread, Mr Lorgat said, "We don't believe that it is widespread and in few instances where a few might be committing something we don't want to see, we will act. Let's see what the evidence we have."

"I do not see this as a tip of the iceberg but we must learn from this. We need to address integrity and root out corruption from cricket," added Flanagan.
