Davido's involvement in the death of Tagbo Umeike, if found guity could land him in prison for life, going by Nigeria's criminal code.
The authorities allegedly re-invited the singer over his participation in the death of his friend Tagbo whose corpse was supposedly pitched at the hospital.

According to the information gathered, the car that conveyed the deceased to the Lagos Island General Hospital was recovered from Davido's Lekki house.

The singer denies his involvement in the scenario but a legal practitioner has revealed to media men that it is early to preempt what the police might bill Davido for, a manslaughter charge might be likely if it's disclosed that he knows about the death.

‘I don’t think it can fall under ‘murder’, according to the legal practitioner.‘If the police say the Tagbo died of suffocation because he was locked in Davido’s car. That would be a manslaughter. Murder would mean it was premeditated. Manslaughter means it could have been unknowingly done. But again we don’t know yet what the police will charge him with.’

Tagbo Umeike was said to have been at a lounge to celebrate his birthday when he became unconscious and was brought in to the premises of the hospital by three other associates of Davido, Tunde Usutu, Agbeje Olaoye and Idris Busari in a vehicle that has since been recovered from the singer’s home.

The Nigerian Criminal Code expressly states what is defined as manslaughter and what the punishment could be. Section 317 defines manslaughter as ‘A person who unlawfully kills another in such circumstances as not to constitute murder is guilty of manslaughter.’

Section 320:2 also states that ‘Any person who- with intent unlawfully to kill another does any act, or omits to do any act which it is his duty to do, such act or omission being of such a nature as to be likely to endanger human life; is guilty of a felony, and is liable to imprisonment for life.’

In addition, Section 326:3 adds that is guilty of a felony, and is liable, to imprisonment for life.

It isn't the best of times for Davido in couple of days following the death of Tagbo, two other friends that died in similar manner, with the authorities regaining their corpses out of a car after a night out.
