French police have arrested 81 people amid Tuesday's mass demonstration against a labor reform bill, local media reported Tuesday.

Earlier in the day, a mass rally took place at 14:00 p.m. local time (15:00 GMT), with hundreds of thousands protesters marching from Bastille to Place d'Italie.

Between 64,000 and 200,000 people took part in the demonstration, Europe 1 media outlet said citing its sources in police. Some 2,500 police officers have been deployed to keep order.

Earlier it was reported that some 30 people were detained by police, with 27 detained before the demonstration at inspection points through which all participants of the movements are checked.

Later on Thursday, the upper house of the French parliament adopted a revised version of government's controversial labor reform bill.

In recent months, France has been hit by massive long-standing nationwide protests and sporadic strikes over a bill on the labor reforms, which seek to extend working hours, impose a cap on damages in cases of unfair dismissal as well as remove barriers to firing employees on economic grounds.
