A Boston man has admitted killing a 72-year-old pensioner following an incident at the town's bus station.
Russell Read, 38, of Castle Street, denied the murder of Joao Costa but admitted manslaughter.
Mr Costa, of Porcher Way, Boston, was treated for head injuries after being attacked in the early hours of May 11 and died two days later in Pilgrim Hospital.
Adrienne Lucking, prosecuting, told the hearing that the Crown was not in a position to establish that Read intended to kill or cause serious injury when he delivered what she described as "moderate" punches.
She said that, as a result, the prosecution accepted the manslaughter plea.
Judge Michael Heath adjourned sentence to a later date and Read was remanded in custody.
