Police have been investigating after a man was found at an address in Lostock Hall with injuries which he later died from.
He was taken by ambulance to Royal Preston Hospital where he was pronounced dead.
Olympic champion Sir Bradley Wiggins is optimistic of success in the Road World Championships time-trial in Ponferrada on Wednesday.
Wiggins finished second to Germany's Tony Martin, the Olympic silver medallist, in Florence last year but is confident the 47.1-kilometre route favours his attributes this time around.
"I'm in better shape than last year," the 34-year-old Wiggins told BBC Sport.
"It's quite mountainous and suits me more than Tony. Every year I think this might be the year but you never know. That's why I like it."
Wiggins is joined in the race by Commonwealth Games champion Alex Dowsett.
The Londoner beat Dowsett to the British title in June and won a short Tour of Britain time-trial last weekend.
"This year's course is a lot different to last year's, which was long and flat," added Wiggins, who did not ride the Glasgow 2014 time-trial.
"You have to think more on this course. There's no room for error.
"You need to have enough in the tank for the end. It's challenging, a true test of the time trial."
A man has been found dead at an address in Lostock Hall, Preston.
Police were called after reports of a disturbance at Albrighton Close in Lostock Hall, on Monday night. A 21-year-old man has been arrested.
A Lancashire Police statement said: "Police and paramedics attended and found a man with serious injuries.
He was taken by ambulance to Royal Preston Hospital where he was later sadly pronounced deceased.
A post mortem will be carried out in due course to establish the exact cause of death.
A 21 year old man was located near to the scene and arrested."
Prince Harry was also presented with a pottery pig at the WellChild awards by a girl from Southport. The ornament was designed to look like him, with the addition of curly red hair and a suit and tie.
Olivia Ruston, who won a young hero award for caring for her severely ill sister, said: "I wanted to make him something to say thank-you for all the work he does for WellChild.
"He said he really liked that it looked like him."

Prince Harry was won over by a young boy from Lancashire who greeted him with a hug at an awards ceremony to recognise the courage of seriously ill children and their families. The Prince met with winners of the 10th annual WellChild Awards at the Hilton in Park Lane, central London.
Four-year-old Carson Hartley from Oswaldtwistle, who has a heart defect and is fitted with a portable ventilator, wasted no time in running straight up to the Prince and wrapping his arms around his legs.
The pair then exchanged a number of high fives while the Prince chatted to Carson's parents about his complex heart condition.
His mother Kirsty said: "We were worried he was going to high-five Prince Harry in the face he was so excited.
"Harry got down on his knees and had a big smile on his face while he was chatting to Carson, he couldn't believe how active he was despite all the conditions he has.
"He said he thought he was inspirational for still being so happy, but he also said that parents must be recognised too for how hard they work, which was really nice to hear."
The awards recognise the courage of children and young people living with serious illnesses as well as the dedicated families, nurses and doctors who care for them.
