The reward is being offered by Sussex Police and Sussex Crimestoppers, with them each offering £5,000 for the arrest and conviction of the man.

Major Crime Branch detectives, who are leading the investigation in to a series of attacks on women in Hastings, are now examining a further six offences to the series of ten attacks earlier publicised.

Although not formally linked, the offences bear striking similarities.
They are also exploring a further five.

The additional offences have all taken place in Hastings and stretch back to August 2006.

DCI Trevor Bowles said: "I feel sure that someone in Hastings, a family member or friend of this man has information which will lead police to arrest and charge him for these violent offences.

"Someone in the town knows who he is. It is clear that this attacker knows the town well. I believe he may live, have family or friends here, or work in the town.

"The willingness of this man to use unprovoked violence against women is a great concern and we urgently need to find the man responsible.

"We know he is white, in his 20s or 30s, and has dark hair that is longer on the top than the sides. He sometimes wears a hoodie.

"Attacks of this nature are unusual, and it is for this reason that this pattern of offending stands out.

"We must find this man and I need the help of the public in giving me the information as to who and where he is."

Information relating to this series of attacks can be provided to Crimestoppers anonymously on 0800 555 111, or direct to Sussex Police, on 0845 60 70 999 quoting Operation Medium.

Sussex Crimestoppers chairman Don Edwardson said: "Sussex Crimestoppers is keen to support Sussex Police in bringing the person responsible for these horrendous attacks to justice.

"If anyone does have any information about who is responsible they can call Crimestoppers on 0800 555 111 with a guarantee of anonymity.

"No one will be asked for their name, no calls will be recorded and no calls will be traced."
