Bahrain has arrested more than 22 people since February for participation in demonstrations against the Al-Khalifa regime.

“The arrests were made in Shiite villages and were related to alleged acts of violence since late February,” said a police statement carried late Saturday by BNA state news agency.
  
In one of the arrests, police detained six people “suspected of participating in a March 7 terrorist attack on police patrols in the village of Maqaba, west of the capital Manama,” it said, adding security forces were still searching for other ‘suspects’.
  
Others were arrested over alleged attacks on police with petrol bombs and metal rods.
  
Police also arrested two people suspected of blocking roads and setting tyres ablaze in the area of Dair, close the airport, on April 14, when demonstrations intensified against Bahrain hosting the Formula One Grand Prix race on April 21.
Al-Wefaq, the main Shiite opposition formation, said on Saturday that police arrested 14 people during raids on Thursday and Friday.

The Bahraini uprising began in mid-February 2011, when the people started holding massive demonstrations against the Al Khalifa regime, which promptly launched a brutal crackdown on the peaceful protests and called in Saudi-led Arab forces from neighboring states to help quash the revolt.
