New Delhi (Agencies): Delhi Police on Thursday announced a reward of Rs 25 lakh for anyone with information in the September 19 Jama Masjid attack case, that occurred there and increased the reward from Rs 10 lakh to Rs 30 lakh for clues on firing at Taiwanese tourists.

With this, the total amount of reward for credible information related to the attack has gone up to Rs 55 lakh.

Police said the information should come to them within a year.

The two incidents where unidentified motorcycle-borne attackers shot and injured two Taiwanese nationals outside the Masjid and a crude pressure cooker bomb blast took place in a car parked nearby created scare among Delhiites ahead of the 2010 Commonwealth Games.

Commissioner of Police B K Gupta announced that Delhi Police will give a cash reward of Rs 25 lakh for anyone who may give information or clues about any person involved in the car blast on September 19.

A car went up in flames when a "crudely-circuited" pressure cooker bomb exploded about 50 metres away from the Jama Masjid where the firing incident took place two hours earlier.

Though police and other investigating agencies suspected the involvement of Indian Mujahideen, no one has been arrested yet in the case by the Delhi Police Special Cell which is probing the case.

Gupta also announced that he has enhanced of the amount of reward from Rs 10 lakh to Rs 30 lakh for any information on the firing incident that injured two Taiwanese tourists.

A month after the incident, Delhi Police had in October last year announced a reward of Rs 10 lakh for information about the two bikers who fired at the tourists or anyone who helped the attackers.

Though police investigated whether those people who sent the Kashmiris to Delhi were involved in the firing incident, no breakthrough was made in this direction.

Investigators have questioned over 50 people in connection with the strikes but "no concrete" headway has been made in the probe while several teams had gone to Uttar Pradesh and Mumbai to find some links in the case.
