For the second time in a week, a Soviet police guard Thursday manhandled a U.S. dilopmat who was trying to enter the embassy here, American sources said yesterday.

Meanwhile, Soviet authorities have ordered American businessman F. Jay Crawford to report to prison Monday for further interrogation in the illegal currency exchange case against him, according to Western diplomats.

Friends said that Crawford, who is the representative in Moscow for the International Harvester Co., would report for questioning Monday morning at Lefortovo Prison, where he spent 15 days in June.

In the latest incident involving Soviet police and an American diplomat, sources said that on Thursday, a police guard physically restrained a U.S. official from entering the embassy grounds despite intervention on the official's behalf by a State Department interpreter, a Soviet employe of the embassy and even another Soviet guard, who tried to restrain his colleague.

The U.S. official, Harold Burman, a member of a group planning construction of a new embassy, carries a diplomatic passport. He has been here a month.

According to sources, as Burman approached an embassy driveway, the guard put his hands on Burman's shoulders, and persisted in preventing the official's entry for several minutes.

The embassy has formally protested to the Soviet government over what it termed a growing pattern of "heavy-handed interference with access to our embassy" involving at least five incidents.

Burman's confrontation follows four other instances of harassment by Soviet guards of U.S. officials.

July 20 a Soviet policeman chased second secretary Raymond Smith on to embassy property, grappling with him.

A day later, a guard blocked access to the embassy to University of Wisconsin professor Gabriel Kojoian, who had just completed seven months of study in Soviet Armenia on an exchange program.

Embassy sources reported there had been two other incidents recently, one involving an American tourist who was blocked from entering the embassy.

Under the Vienna Convention of 1961, which was signed by the Soviet Union, diplomats are supposed to have free access to their embassies, physical force is not supposed to be used to deny entry, and police are prohibited from entering embassy property to exercise their authority.

The latest incident came amid a growing strain between the United States and the Soviets that has resulted in a spate of incidents of harassment against U.S. citizens here.

One of those incidents involved the arrest last month of Crawford, the International Harvester respresentatives here. He was pulled from his car on a Moscow street the night of June 12 and charged with dealing in currency on the black market.

Crawford, 37, has denied the charges, and International Harvester said Monday that it has suspended trade talks with the Soviets and was asking other companies to protest to the Kremlin over Crawford's treatment.

Crawford will be accompanied Monday by U.S. consular officals, sources said.

Crawford reportedly hopes the Monday session will be limited to the return of personal property confiscated from his hotel room and office, but diplomatic sources say it is more likely the Soviets will interrogate him on the exchange charges.
