The killings have sparked tension in the state capital.
Two leaders of the Hausa community, who spoke on condition of anonymity, said their members could identify the hoodlums.
The sources claimed that three men, a woman, and teenager were killed during the attack.
It was learnt that security operatives comprising the police, Department of State Services and soldiers have been deployed in the area to avert a reprisal.
The police, on Saturday, said two suspects, believed to be members of the Indigenous People of Biafra, had been arrested in connection to the killings.
A statement by the Delta State Police Public Relations Officer, Andrew Aniamaka, noted that the attackers were a three-man gang.
Aniamaka said the leader of the gang was at large following the arrest of the two suspects.
While commiserating with the families of the deceased, the police spokesperson disclosed that five persons sustained injuries, adding that they were receiving treatment at the Federal Medical Centre, Asaba.
“The Delta Police Command in the early hours of Saturday arrested two suspects namely: Abraham Ndudi, 24, from Kwale, Delta State; and Okereke Ifeanyi, 21, from Ogbaru in Anambra State for their involvement in the dastardly shooting and killing of four persons at Abraka Market, Asaba.
“The suspects, who were arrested from their hiding places, are already helping the police in their investigation. Meanwhile, efforts are ongoing to arrest the third suspect, whose real name is yet unknown but simply identified as ‘Last Burial’.”
The state Commissioner of Police, Mr. Zanna Ibrahim, in the statement, called for calm, assuring residents of the state that adequate security measures had been put in place to ensure the security of lives and property.
