The Kerala High Court has upheld the life sentence awarded to a man for stabbing to death his neighbour whose loud singing of devotional songs was interfering with the convict`s daughter`s studies.

The high court, however, acquitted a co-accused in the case, who had been convicted and awarded life sentence, saying he was not guilty of the offence of murder or of sharing a common intention with the prime accused - the neighbour - to commit a crime.
