Rome , Italy ( CNN ) -- A man tried to enter the hospital room of Italian Prime Minister Silvio Berlusconi overnight , as the leader recovered from being hit in the face Sunday . The man was detained . No further details about him were immediately available but Italian media reported that he was carrying a knife . Berlusconi , for his part , will remain in the hospital at least one day longer than expected , his doctor said Wednesday . The PM will be hospitalized at least through Thursday , Alberto Zangrillo announced , citing Berlusconi 's difficulty eating and ongoing pain . `` Having said this , the clinical conditions of the prime minister are reassuring . We are reassured , not worried . And , I believe I can say that the prime minister will be dismissed tomorrow early afternoon , '' he said . He also said Berlusconi , 73 , would not participate in public events for 10 to 15 days after his release . Berlusconi spent a troubled night with pain in his neck , his spokesman said . His night was `` worse than previous ones , '' spokesman Paolo Bonaiuti said , though he attributed Berlusconi 's unease partially to his enforced absence from work . `` All his life he has been a very hard-working man . To try to keep him still , to keep him off work , is a titanic task , '' Bonaiuti said . Read about Berlusconi 's year of woes . Berlusconi suffered broken teeth and a fractured nose in the Sunday attack , in which a man threw a souvenir replica of Milan 's cathedral at him and hit him in the face . Zangrillo said he does not believe Berlusconi will suffer permanent scars and that his teeth can be reconstructed . Berlusconi 's recovery will take another 25 days , Interior Minister Roberto Maroni told Italy 's Chamber of Deputies , the lower house of the Parliament . The attacker , Massimo Tartaglia , 42 , was arrested shortly after the attack and is now in a Milan prison . Police found Tartaglia was carrying other objects , including pepper spray and a large crucifix in his pockets , which showed the attack was premeditated , Maroni said . Tartaglia had bought the replica of the Duomo di Milano , the city 's central cathedral , at a souvenir shop , he said . Tartaglia attacked Berlusconi `` because he harbored hatred against the premier , '' Maroni said . There has been a climate of hatred against Berlusconi in recent months , the interior minister said , with many anti-Berlusconi Web pages . Maroni said he is thinking of introducing regulations to block them . His words echoed those of Senate speaker Renato Schifani , who visited Berlusconi in the hospital Monday and said he was pained by the `` hatred '' that led to the attack . Berlusconi , a conservative media mogul-turned-politician , has been dogged by allegations of corruption and is the middle of a messy divorce from his second wife . The three-term prime minister faces trial on tax fraud charges after Italy 's top court struck down an immunity law that shielded him from prosecution . He denies the charges , calling them politically motivated . His wife of 19 years , Veronica Lario , filed for divorce in May after allegations that an Italian businessman hired escorts for the premier and that Berlusconi had attended the birthday party for an 18-year-old girl , with whom he has denied having an inappropriate relationship . Berlusconi remains popular among the Italian public , however , with his approval ratings holding well over 50 percent . He won a third term in 2008 , and his conservative coalition has control of both the Chamber of Deputies and the Senate . CNN 's Hada Messia contributed to this report .
