TEHRAN (Reuters) - Iranian police will crack down on women in Tehran flouting Islamic dress codes with winter fashions deemed immodest, such as tight trousers tucked into long boots, an officer was quoted as saying on Saturday.

"Considering the start of the cold season and its special way of dressing, police will start early next week a drive against women who wear improper dress," Tehran police chief Ahmad Reza Radan was quoted as saying by state news agency IRNA.

"Tight trousers tucked inside long boots while wearing short overcoats are against Islamic codes," the police chief said.

"Wearing a hat or cap instead of scarves is also against Islamic dress codes."

Police officials were not immediately available for comment. The Iranian week begins on Saturday.

Police regularly clamp down on skimpier clothing and looser headscarves in the summer. Usually this is for just a few weeks but this year the campaign has run into the autumn.
