The Tirupur North police on Thursday arrested R. Sadasivam (26) on the charges of robbing A. Sherif, a resident of Thiruvalluvar Nagar.
Mr. Sherif was standing at Kongu Main Road on Wednesday evening.
The police said the accused took away a mobile phone set after attacking Sherif with a knife.
His attempt to take away cash, however, did not work out, officials added.
House of C. Elango at Sivalingam Pillai Layout in Udumalpet was allegedly burgled and jewellery worth about Rs. 35,000 taken away. Burglars gained entry into the house by breaking open a window.
