New security measures hastily set up in West Berlin to try to catch terrorists believed responsible for a prison break and an attack on two lawyers are privately causing concern to some government officials here.

The concern is that the measures are not likely to turn up the terrorists but may damage the isolated city's image and stir up tension among some of West Berlin's 2 million residents.

Since Thursday, when a West Berlin court invoked new anti-terrorist laws that had been enacted by the Bonn parliament in March, police have set up control points at street intersections and crossing points along the wall dividing West Berling from East Berlin and the rest of East Germany. Residents are required, upon demand, to show identity papers and to submit to searches.

The measures were ordered by the West Berlin government after two armed women, identifying themselves as defense lawyers, got into the top security Moabit Prison last Saturday and freed accused terrorist Till Meyer. Police are seeking four women in connection with the jailbreak.

Meyer was one of five persons on trial in West Berlin for the kidnaping of a conservative political leader and the murder of a West Berlin judge four years ago.

On Wednesday, a court appointed lawyer in the trial was shot in the leg by a gunman in a passing car, while a bomb was found under the car of another lawyer.

Yesterday, groups calling themselves "revolutionary cells" contacted West German news agencies and took credit for these two attack. They said more would occur if these court appointed lawyers are not withdrawn from the case, so the suspects can be represented by lawyers they have chosen. The defendants' regular lawyers have been unwilling to comply with security procedures before entering the courtroom, which require removal of trousers and body searchers.

Although nobody speaks of it publicly, the leg-shooting incident may have been either a haphazard shot or the start of an Italian-style campaign of shooting people in the legs to cripple them.
