Saeed was placed under house arrest on January 30 in Lahore.
"I am doubtful of the action because in his statement before a court in Mumbai, David Headley had said that no action was likely to be taken against Saeed and Zakiur Rehman Lakhvi in Pakistan," Nikam told reporters here.
"Headley had even submitted e-mails which he had received from Lashkar-e-Taiba (LeT), which indicated that the action against Lakhvi was an act of hypocrisy," he added.
Saeed was earlier put under house arrest after the 26/11 Mumbai terror attack, but was freed by a court in Pakistan in 2009.
He carries a reward of USD 10 million on his head, announced by the authorities in the US for his role in terror activities.
