Grant, 17, was fatally shot when a party of policemen showed up and cornered a group of men who were under a shed in a yard in Agricola.
Police reported that the youths first discharged a volley of bullets at them, and they returned fire, killing Grant and injuring Romel Bollers.
Police arrested three others, but they were later released after relatives and others met with Acting Commissioner Leroy Brumell.
However, last week, when Agricola residents joined Grant’s relatives and staged a picketing exercise outside the office of the police commissioner at Eve Leary, the commissioner promised to complete a full investigation so that justice would prevail for the youth.
Not satisfied with the pace of the police investigation, the picketers held another protest action outside the police commissioner’s office on Thursday.
The commissioner consequently told the media on Monday that the DPP was expected to return the file shortly.
Police contend that at about 12:10 hrs on September 11, 2012, ranks on a mobile patrol came under fire from a group of men at Caesar Street, Agricola; and the policemen returned fire, fatally wounding Shaquille Grant, 17, of Lot 12 ‘BB’ Eccles, East Bank Demerara, and injuring Romel Bollers, 20, of Brutus Street, Agricola.
A .38 Smith and Wesson weapon was reportedly recovered by the police.
