Mumbai police has been carrying out surprise checks in city hotels following intelligence inputs that some terror suspects from neighbouring countries may have infiltrated to carry out terror activities. Police sources said that documents of Afghanistan and Pakistan nationals pertaining to their stay in Mumbai have been thoroughly verified. About 500 hotels and lodges including Five Star hotels were checked recently to ascertain if any foreign national is staying without proper documentation or carrying out any suspicious activities. Home Ministry sources said these are routine checks as the intelligence inputs are trickling in now and again after Mumbai terror attacks. Asked about the checks at hotels, Director General of Police A. N. Roy said, police is taking precautions to ensure that New Year celebrations pass off peacefully. <br/>
