ASUNCION , Paraguay ( CNN ) -- A second woman stepped forward Monday to say that Paraguayan President Fernando Lugo fathered a child out of wedlock when he was a Roman Catholic bishop . Paraguayan President Fernando Lugo says Monday he will comply with justice on the latest paternity allegation . Benigna Leguizamon said Lugo fathered her son in 2002 in the city of San Pedro . She served notice that Lugo has 24 hours to acknowledge paternity or she will take legal action . `` I am waiting in good will , '' she said in an interview on CNN affiliate Telefuturo TV . `` But if they do n't do something , oh , my God . '' Lugo , 57 , acknowledged last week that he is the father of a 2-year-old child conceived in the months before he stepped down as bishop . He said last week he was making the admission `` with the most absolute honesty , transparency and feeling of obligation . '' Without acknowledging paternity , he expressed similar sentiments Monday about the latest allegation . `` We 're going to act always in pursuit of the truth ... in this private matter , '' he said in a nationally televised announcement on Telefuturo . Last week 's announcement came after a woman filed suit in a southern Paraguay city seeking a paternity test . `` It 's true that there was a relationship with Viviana Carrillo , '' Lugo told reporters , naming the mother . `` I assume all the responsibilities that could derive from such an act , recognizing the paternity of the child . '' Leguizamon , 27 , said Monday that last week 's announcement had encouraged her to come forth . `` When I saw the case with Viviana , I was strengthened to make my accusation , '' Leguizamon said . She said she made the accusation to help her 6-year-old son , who is starting school . She will ask for a DNA test , she said . In last week 's case , Judge Evelyn Peralta said she was treating it routinely . `` It is a case like any other , which involves the president and nothing more , '' she said . `` It will be processed at it should be . '' Some Cabinet members interpreted Lugo 's acknowledgment of paternity as an indication of the change he has promised to bring about to achieve greater transparency in the public sector . `` This is the Paraguay that we want , '' said Liz Torres , minister of children 's issues . `` This is the Paraguay of serious change in which there is no double standard or secrets . It seems to be an example , a very big lesson . '' But some opposition party members said it appeared that Lugo practically had been forced to acknowledge what happened and that he had not done so willingly . Sen. Julio Cesar Velasquez of the opposition Colorado Party called on the Vatican to excommunicate Lugo . Lugo was made a lay Catholic last year , around the time he assumed the presidency .
