Law enforcement agencies have arrested 10 suspects in connection with bomb attacks on Internet cafes in this eastern Pakistani city, police officials said on Monday.
The suspects, who came to Lahore from Waziristan tribal region, Abbotabad and other parts of northern Pakistan, were arrested in Garhi Shahu area of Lahore, officials said.
Punjab police chief Tariq Saleem Dogar confirmed the arrest of the suspects from Garhi Shahu.
He said a "massive operation" has been launched across the province against banned groups and others involved in terrorist activities.
"A good number of suspects have been taken into custody so far," Dogar said, without giving details.
Police have extended a search operation for suspects to the suburbs of Lahore.
DIG (Operations) Rao Sardar Ali Khan said the house-to-house search is aimed at ascertaining how many residents of these areas did not have identification papers.
Consolidated data gathered during the search will be centralised and the record-keeping exercise will be completed in about two weeks, he said.
Khan said the Tableeghi Markaz at Raiwind in Lahore was not thoroughly searched but an extensive terrorism-related operation had been launched in and around the area.
Reports have suggested that militant elements had sheltered at the Tableeghi Markaz at Raiwind before carrying out terror attacks in the city.
Six persons were injured when low intensity bombs went off at Internet cafes in Garhi Shahu and Begum Kot areas of Lahore on Saturday.
The Tehrik-e-Tahafuz-e-Pakistan claimed responsibility for the attacks.
Meanwhile, security at Shia 'imambargahs' or prayer halls in Lahore has been intensified in the aftermath of a suicide attack on an imambargah in Sargodha that killed one person and injured nearly 20 more.
