Azerbaijan, Baku, May.11/ Trend F.Karimov/
Police has surrounded the office of Iranian ex-president Mohammad Khatami, the Kalameh website wrote.
"The presence of law enforcement forces around Mohammad Khatami's office has created an tmosphere of security and intimidation," according to the website.
MP Mohammad-Reza Tabesh, who is a relative of Khatami, told ILNA that the police is present there to maintain security and order in the neighborhood.
The incident has occurred on the final day of registration for presidential election. Reformists and conservatives have called Khatami and other ex-president Rafsanjani to register in the election.
Tabesh rejected rumors about any attacks on Khatami's office, saying the law enforcement forces have nothing to do with his office.
During the past days, Khatami has referred to Rafsanjani as the best choice for the post of presidency.
Iran will hold the 11th presidential election on June 14, 2013.
The voters will select the successor of the current President Mahmoud Ahmadinejad, who is not able to participate in the elections for the third term according to the country's constitutional laws.
The president of Iran is elected for a four-year term in a national election and the Guardian Council vets the candidates for qualifications.
