A private legal practitioner has claimed that the National Chairman of the National Democratic Congress (NDC) violated no law when he declined a police invitation.Mr. Martin Kpebu said “speaking pure law Samuel Ofosu-Ampofo is not obliged to go. It is an invitation so he may decline or accept to attend.”Wading into the controversy, Joy News’ news analysis programme Newsfile, Saturday, he said aside from the legal aspects of the conversation, he claimed that the police action lacks tact.According to him the manner in which the invitation was done can heighten the political temperature which has been rising.“We are begging Maame Yaa Tiwaa Addo-Danquah, (CID boss) that with security matters we don’t joke with them. These things affect the citizens. Police should be tactful when dealing with politically exposed people.”The Chairman of the National Democratic Congress is being investigated for his alleged involvement in crimes of kidnapping and arson. According to the police a suspect has mentioned his name.“Some persons picked up for interrogation and investigations have mentioned your name as part of a grand scheme designed to cause fear and panic in the country.“We look forward to your co-operation in this matter of National Interest,” the police wroteBut Mr Ofosu-Ampofo has refused to cooperate with the police. Lawyers of the embattled National Chairman have written to the police to formally inform them of their decision not to honour the invitation which expired at 2 pm on Thursday.That is not all. The Council of elders of the NDC has served a public notice that no member of their party, including former government appointees, will henceforth assist the police in any investigation.Suggesting an alternative for the invitation, Mr Kpebu said police practice makes room for the police to invite certain people within the ranks of the NDC chairman either quietly or pay him a visit to discuss their concerns.He said it was in that spirit that a suspect in the murder of Ahmed Hussein-Suale was interrogated at a place of his choosing.Mr. Kpebu believes the constitutional provision which makes room for police to follow some protocol before a parliamentarian can be arrested is only to demonstrate how the constitution expects certain persons to be treated with dignity in the discharge of police work.Mr. Samuel Ofosu-Ampofo is currently standing trial for the contents of leaked recording which the police has described as criminal.The voice which has been attributed to the NDC chairman despite his denial is heard planning various proscribed acts.
