The police have deployed more men to Agbogbloshie to maintain calm following violent clashes that have led four people, including a policeman injured.

The clashes began at the Onion Market here in Accra, Tuesday morning.

The violence, triggered by an assault on a young girl, is said to have ethnic undertones.

Joy News' Kwetey Nartey who was at Agbogbloshie narrated that the young girl had gone to ease herself at a portion of land said to be occupied by some Zabarima traders.

She was beaten up and sent away by one of the traders.

The girl went to tell her father who led her back to where she was beaten.

Unfortunately, the father was hit with a hammer, triggering a violent confrontation, Nartey reported.

The girl's people mobilised and attacked the Zabarima traders in retaliation.

There were exchanges of gunfire by persons from the two groups.

When the police intervened, the factions began pelting them with stones.

One of the police officers was said to have been hit by a stone.

Police chief, DCOP Tetteh Yehonu, said no arrests had been as of Tuesday afternoon.

He said the police were concentrating on restoring calm to the slum.

"So far no arrest. We want to calm tempers," the Accra Region Police Commander told Joy News.

"We will continue to be on the ground at least to make sure that tempers go down."

He dismissed earlier reports some people had been killed. "There is nothing to show anybody is dead," he indicated.
