A dispute over a piece of poromboke land ended in murder of brothers at Keezhavangaram village near Siruganur on Wednesday.
N. Arumugam (60) and his younger brother N. Tirupathi (50) died on the spot in the attack. The police have detained the accused R. Kanagaraj (55), D. Madhubalan (33) and Durairaj.
Sources said Kanagaraj had obtained patta for a three cent poromboke land at the village.
The brothers put up a shed on the land which was questioned by Kanagaraj.
A wordy tiff broke out between them with Madhubalan and Durairaj coming in support of Kanagaraj.
The quarrel soon took a turn for the worse.
