A Pakistani national accused of spying was arrested from the old city area of this industrial hub in Punjab on Thursday, police said.
Further details were awaited as police officers said the Pakistani national was being interrogated.
The arrest came nearly 12 days after Chandigarh police arrested Pakistani spy Kashif Ali from the city.
Ali had been living in Chandigarh for over two years in a rented accommodation in Sector 44 under the fake name of Pawan Kumar.
His accomplices in Delhi and Chandigarh had helped him procure a voter identity card and a permanent account number (PAN) card.
