KARACHI, Sept 26: The police have begun investigating the role of the only survivor of the Rimpa Plaza massacre as he has been continuously changing his statements since on Wednesday. The agents of federal Investigation Agency (FBI) have also joined the inquiry beside the Pakistani investigators.

Sources in the police investigation wing said Robin Piran Ditta, was the only eyewitness to the horrible incident. The police got the sketches prepared of the possible attackers with the help of Ditta. He told the police that there were three armed men who committed the crime.

However, the investigators were suspecting that Ditta had been concealing some information and he had tried to misguide the police. He told the police that all of the killers were Urdu-speaking. Contrary to his statements, the sketches prepared with the help of Ditta appeared to be Sindhi and Punjabi-speaking. The investigators said they believed Ditta had got prepared misleading sketches.

They said the differences in the statements of Ditta had created doubts. Ditta had told the police that he went out to buy tea and when he came back, two armed men caught him and beat him. The armed men then escaped. Later, he came to know about the incident.

After some time, the investigators said Ditta retracted from his earlier statement and said he was tied with the chair beside his other colleagues and as first, who was sitting beside him, was shot, he fell unconscious. His chair on which he was sitting also rolled down. He was untied by the police. Later, on a query that who had opened the door when another worker Rahim Bux Azad knocked the door, Ditta said he did that. The investigators questioned him that how could he open the door when he was tied with the chair. To this, he had no answer.

The sources said the leaders of Christian community in the country had been continuously exerting tremendous pressure on the police to release Robin Piran Ditta. They alleged that he had been subjected to torture. “We have taken him (Ditta) to a doctor for a medical checkup and he is all right,” said a police officer.

An FIR was registered at Garden police station on the complaint of Dr Zafar, administrator of Idara Amn-o-Insaf. He mentioned in the FIR that some personal files were also missing from the office.

The sources said the Federal Investigation Agency (FBI) agents and the officials of the US consulate also visited the place of incident to inspect the crime scene. They minutely examined the place where the killings took place. They also obtained finger prints from different things including table, chairs, adhesive tapes, etc. They took some evidence with them for further examination.

Seven people were shot dead on Wednesday morning and another was seriously wounded in the office of a Christian NGO Idara Amn- o-Insaf at Rimpan Plaza on M. A. Jinnah Road. The killers did not kill Robin Piran Ditta, who was peon and watchman of the office.

Meanwhile, the police investigators including the city police chief Asad Jehangir and DIG Investigation, Fayyaz Leghari, visited the place of incident and demonstrated a fire to know whether the killers had their pistols silencers.

The outer door of the office was locked and a bullet was fired. The sound of the fire was heard outside the office and in the other offices, which indicated that the killers had their TT pistols silencers.
