Robbers looted gold ornaments and cash from six jewellery shops and injured a policeman at Kalashkathi Bazar in Bakerganj upazila early yesterday.
The shops are Rajlaxmi Gold House, Dolon Alankar Bhavan, Kalashkathi Alankar Bhavan, Nittananda Alankar Bhavan, Paul Alankar Centre and Sonar Gahana Bhavan.
Locals said the robbers, in guise of DB police, raided the bazar and confined the traders to a medicine store there and looted 33 tolas of gold ornaments, 100 tolas of silver and Tk 10 lakh from the jewellery shops.
A patrol team of police, led by Assistant Sub-Inspector (ASI) Md Jasim Uddin, at the market then challenged the gang. At the time, the robbers beat the ASI and the president of the bazar committee.
Seriously injured ASI was rushed to Barishal Sher-E-Bangla Medical College Hospital.
Jasim was later taken to Dhaka by an air ambulance as his condition worsened, said Superintendent of Police (SP) Md Saiful Islam.
They were raiding different areas to arrest the gang, said the SP.
