On Dec. 16, two boys were sexually molested by a middle-aged man in the basement of Lisner auditorium on the campus of George Washington University.

Five days later, an attorney in a downtown law firm contacted District of Columbia police. The lawyer said he represented the man who had committed the acts on the two boys, ages 10 and 11. The attorney, who refused to identify his client but said he comes from a prominent family, wanted to make a plea bargaining agreement. The attorney was referred to the U.S. attorney's office, which refused to agree to the plea bargain. The attorney left, refusing to name his client.

Thus far, there has been no arrest in the case and city police are furious.

"As far as we are concerned, it's obstruction of justice," said one police investigator.

D.C. police on Friday released a composite drawing of the suspect. The suspect is a white male in his 40s, about 6 feet tall with a stocky build. He has a ruddy complexion. On the day of the incident, he was wearing a blue ski jacket, grey pants and brown shoes.

According to an investigator, the drawing was done a day after the incident, but was only released two days ago because of printing problems.

The incident occurred about 6:30 p.m., on Sunday, Dec. 16, according to police. The boys were in the basement of Lisner during a break in a performance to get sodas.

While at the soda machine, the man sexually molested them.

The boys, who live in the Washington suburbs, were frightened and told the man they had to return upstairs and fled.

"If they had not been as cool as they were, there is no telling what would have happened," said the mother of one of the boys.

Five days later, police sources said, a detective in the department's sex investigation squad received a telephone call from James Michael Bailey, a lawyer who said he represented the man police were seeking in connection with the case. Bailey said his client was frightened by the experience, and had never done anything like that before, the sources reported. They said Bailey told police that the man came from a prominent family and that he would turn himself in if he could be promised that he would be released.

Bailey declined yesterday to comment on the account by police sources.

The attorney then followed up the call with a visit to police headquarters at 300 Indiana Ave. NW, where he talked with the investigator a second time.

At one point during the conversation, the lawyer said if police tried to find out who the suspect was efforts would be made to get him out of town, police sources reported.

Bailey and another attorney in his firm were taken to the U.S. Attorney's office, where a plea bargain agreement was turned down.
