The Indian police have linked the attack on the Israeli diplomat's wife in New Delhi last month to a failed bomb attack in Bangkok, allegedly by a group of Iranian men.

Israel had blamed Iran of carrying out both the attacks as well as another failed bombing attempt targeting Israeli officials in the former Soviet republic of Georgia. However, Iran has denied its involvement in the incidents.

Earlier, India too had refused to connect the two incidents or blame Iran for the bomb blast which injured the diplomat's wife and three others. The bomb was attached to the back of her car by a magnet.

However, investigations by the police are increasingly centering around the Iranians, and arrests and initial evidences all point towards a connection between the Indian and Thai bombings.

Last week the police arrested an Indian journalist Syed Mohammed Kazmi, who freelanced for Iranian news organizations, to investigate his alleged links to the bombing.

Indian police issued arrest warrants for three Iranians who are accused in the New Delhi bombing, earlier this week. The suspects reportedly have left the country and India is reportedly seeking the Interpol's assistance to trace and extradite the men for further probe.

Delhi Police Commissioner B.K. Gupta told reporters Friday that one of the three men, identified as Housan Afshar, had been in contact with Masoud Sedaghatzadeh, who was arrested in Malaysia and is accused of involvement in the Bangkok blast, according to local media reports.

We have informed the Iranian ambassador of these developments so as to seek the cooperation of the Iranian authorities in bringing those involved in this dastardly attack to justice, he said in a statement.

Police believe that Sedaghatzadeh is the mastermind behind the plots and his arrest in Malaysia helped them connect the dots in both the terror plots.  Kazmi used to be in touch on telephone with both Afshar and Sedaghatzadeh, said the police.

He has been arrested as a facilitator and for being a part of the conspiracy. His questioning brought to light that he has been in contact with persons of Iranian origin involved in the attack for some time, Gupta told reporters, according to the local media reports.
